More Violence

So, basically, what I've learned so far from the Old Testament is that the strongest one survives. Its funny because I'm starting to read things I didn't know about the bible, things that I was never told. No wonder they hide most of the Old Testament from little kids, if they knew about all the violence that went before Jesus, they would freak out and be really confused (I know I would!).
Sometimes, I get the impression that God just gave up on us and let us kill ourselves, other times, I think he's trying to help, and he ends up making matters worse. I think we have started to look at God and an equal to us, that's why we question him so much. But how can we not question him if all he does is contradict himself? "Thou shall not kill", he's sure following this commandment when he helps David, isn't he? (That was sarcastic). So, he tells people to follow his rules, otherwise they'll turn out worse, and later he tells people to break the commandments he just gave them... Basically, the commandment God is telling people to follow is eye for an eye, violence for violence.
