Human beings inflict pain on others who have done nothing wrong to them.
The God of the Bible inflicts pain (through hell) on those who continue to hurt others after He has given them a chance to change (repent).
Who is the bad guy here? Do not blame God for punishing you for something you have done, even while you are hurting other people around you for things they have not done.
You are in no position to judge God.
God loves you this much:
You see, at just the right time, when we were still powerless, Christ died for the ungodly. 7 Very rarely will anyone die for a righteous person, though for a good person someone might possibly dare to die. 8 But God demonstrates his own love for us in this: While we were still sinners, Christ died for us. (Romans 5:6 NIV)
