I will answer the suffereing question first.
There can be no Good without evil, no happiness without pain. I have suffered quite a bit, but as a result I can appreciate some things that others take for granted.
Some suffering is this ballence. Some suffering, however, is Free Will. God gave us free will, to do what ever we want to do. That includes murder. So, other than our own moral compass and the knowledge of consequence, there is nothing to stop people doing malicous things to each other.
Okay, dreams for the future. I am training to be a teacher, but I really want to work with kids with emotional and behavioural problems. I have a strong interest in Film, and want to amke films, but I also feel drawn to setting up an organisation which runs workshops in film and art as a kind of therepy and to help give meaning to their lives.
