3.) Why doesn't God destroy the Devil, if its the Devil's fault? Why does God throw all the people in Hell, if those people don't believe in him? (you know we should have free will to decide what we want to believe, also some people in Africa can't ever hear of God, because there is nobody to explain them, does this mean they should go to Hell?)
The short answer is that this fire-and-brimstone belief of hell is a western Christian idea. I'll explain that in a moment.
Regarding salvation, the 2,0000-year-old constant belief of the Orthodox Church can be summed up in the following phrase: "We know where salvation is, but we don't know where it is not."
In other words, all salvation is through Christ, through His church. But, at the same time, that doesn't necessarily mean that all those within the Church are "automatically saved" or that those who don't know of Christ are "automatically damned." Whoever ultimately ends up with eternal life, whether within the visible Church or completely ignorant of Christ, will have life because of Christ.
So, the super-short answer is that nobody knows who will have eternal life. To quote a famous saint: "There are many wolves within the Church and many sheep outside the Church."
Going back to the hell question, I'll answer this question with a copy/paste post of mine from another place.
The common perception of Hell is that of a "fiery abode" separate from God, where the sinner and nonbeliever shall suffer unspeakable fear and pain for all eternity. According to western Christianity, all those who are separated from God at the time of death will be deposited to this murky realm of horror and left to rot forever.
But is this what Christianity always taught? Is this what all Christians believe?
To find the answer we need to look at the history of Christianity.
During the first millennium, there was essentially one main Christian orthodoxy, the universal (aka "catholic") faith. Whether you lived in France or India, eastern Africa or central Asia, Christian churches adhered to the same fundamental beliefs and practices. There were priests and bishops, and there were sacraments. The basic doctrines were the same throughout; all believed in the Real Presence of the Eucharist, and all believed in the concept of apostolic succession.
Western Christianity--the church that existed in western Europe--was largely influenced by Latin philosophy. During the early centuries of Christianity, theologians in the west gradually began to take a very legalistic approach to their faith. With the level of meticulousness we might expect in a lawyer today, they worked to define, in the most specific terms possible, various doctrines of faith. (The fifth century St. Augustine, developer of the doctrine of "original sin," is probably one of the more famous examples of this.) It was these Latin theologians who came to the conclusion that Hell must ultimately be what we today in the west think of it as: a realm of fire and torture.
At the end of the first millennium, the western church, which had developed belief that the bishop of Rome (the "pope") was the divinely-ordained head of all Christendom, effectively split away from the rest of the church in an event known as the "Great Schism." From then on, we've been left with two streams of orthodoxy: the western catholic, or "Roman Catholic" Church, and the eastern catholic, now referred to as the "Orthodox" Church.
So, if Orthodox Christianity wasn't influenced by the great theologians of the west (St. Augustine wasn't even translated out of Latin until the 14th century, for instance), then what exactly does the Orthodox faith believe about Hell?
According the website of the Orthodox Church of America (oca.org):
For those who love the Lord, His Presence will be infinite joy, paradise and eternal life. For those who hate the Lord, the same Presence will be infinite torture, hell and eternal death. The reality for both the saved and the damned will be exactly the same when Christ comes in glory, and all angels with Him. so that God may be all in all.(I Corinthians 15-28) Those who have God as their all within this life will finally have divine fulfillment and life. For those whose all is themselves and this world, the all of God will be their torture, their punishment and their death. And theirs will be weeping and gnashing of teeth.(Matthew 8:21)
In other words, the Orthodox faith teaches that all humans, the saved and the damned, will spend eternity in the fiery presence of God. Hell is not some "place" God created. It's something we create with our own free will. The nature of this fire depends not on the fire itself, but on the disposition of the observer. Though there is no "official" teaching about Hell in Orthodoxy (Orthodox thought doesn't require exact answers for these sorts of questions), this concept of Hell has been firmly believed by the Orthodox since the earliest times.
To quote St. Isaac the Syrian (613-700):
"It is totally false to think that the sinners in hell are deprived of God's love. Love is a child of the knowledge of truth, and is unquestionably given commonly to all. But love's power acts in two ways: it torments sinners, while at the same time it delights those who have lived in accord with it... those who find themselves in hell will be chastised by the scourge of love. How cruel and bitter this torment of love will be! For those who understand that they have sinned against love, undergo no greater suffering than those produced by the most fearful tortures. The sorrow which takes hold of the heart, which has sinned against love, is more piercing than any other pain. It is not right to say that the sinners in hell are deprived of the love of God. But love acts in two ways, as suffering of the reproved, and as joy in the blessed!"
Hell as some torture chamber built by a vengeful God is just one of the erroneous teachings that western Christianity has spread into the world. For many of us in the west, even those with no religious affiliation, the legalistic way of thought is so embedded in our culture that it's difficult to think any other way.
4.) Why does God 'hate' Homosexuals, if we are all equal and God created us the way we are?
God hates nobody. Think of the famous passage in the Gospel when the authorities bring forth a prostitute to Christ to test Him. They say, "Moses tells us to stone this woman, but what do You say, Oh great Teacher?"
Jesus said, "He who is without sin, let him cast the first stone."
Also,
To some who were confident of their own righteousness and looked down on everyone else, Jesus told this parable:
"Two men went up to the temple to pray, one a Pharisee and the other a tax collector. The Pharisee stood by himself and prayed: ‘God, I thank you that I am not like other people—robbers, evildoers, adulterers—or even like this tax collector. I fast twice a week and give a tenth of all I get.’ But the tax collector stood at a distance. He would not even look up to heaven, but beat his breast and said, ‘God, have mercy on me, a sinner.’ I tell you that this man, rather than the other, went home justified before God. For all those who exalt themselves will be humbled, and those who humble themselves will be exalted."
Remember what He said:
"Therefore be merciful,
Even as your Father is also merciful.
Don't judge,
And you won't be judged.
Don't condemn,
And you won't be condemned.
Set free,
And you will be set free.
Give,
And it will be given to you: good measure, pressed down, shaken together, and running over, will be given to you. For with the same measure you measure it will be measured back to you."
