God 'hates' no one.
Man was made in and still is made in the image of God (James 3:9) meaning man shares certain traits that God possesses as in rational thinking, creative mind and free will.
Free will does NOT mean man has the freedom to do as his will pleases but his will must operate within the boundaries/laws of nature, of man and of God.
Free will is choosing between 2 or more options. Of course, free will choices are not made in a vacuum but there are external influences that can have an effect upon a person choices but in the end a person still makes his own free will choices.

Rendering each according to their works is not "mercy" because if all received according to their works, all would be under God's wrath. No one would be saved."
That is not quite the case ,Romans 2:6-11. Not all in this context are rendered as being lost..."
Who will render to every man according to his deeds: To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life:....But glory, honour, and peace, to every man that worketh good, to the Jew first, and also to the Gentile:"
Man determines his own eternal fate by the TYPE of works he peforms, two different types of works are found in the context of Romans 2, good works, evil works. On judgement day, all God will do is hand out the sentence that fits the type of work a man, of his own free will, chose to do.
Christ tasted death for every man Hebrews 2:9 but every man will not be saved because every man will not use his free will to obey Christ Hebrews 5:9 in order to be saved.
THe BIble does not teach one must first have a literal indwelling of the Holy Spirit before one is able to believe. Such an idea would make God respecter of persons. Romans 10:17 faith comes by hearing God's word not by a literal miraculous personal indwelling of the HS apart from the word or hearing of the word.
