Bad People are myths

I am psychology major here in college and I'm studying aggression at the moment. Reading about all the shootings that happened, rape and all this horrible stuff; many people would've been quick to grow angry with the offender (I'm definitely one of them) but for some reason today my heart broke for them instead. How much pain they must have went through to become this way, how much hurt they must have had in their lives, the misunderstandings, the loneliness, the confusion...it's not an excuse for what they have done and the pain they have caused to others but it is something worth considering. To say the world is full of bad people, I honestly disagree. But I do see really broken and lost people. People who desperately need God in their lives to guide them and comfort them, just to let them know that someone does love them, that they are worthy. When I read these stories, my heart just hurts, I wonder how much this must hurt God...how does God go through all this heartache and still love mankind, he sees us as we hate the people we caused to become lost and broken. God's unconditional love amazes each and every day.
