Sadly you're not interpreting the bible correctly. That's a common problem these days. The bible is not written for reading it word by word, but rather reading it in the context of both the time it was written in, and the context around it. What you are not taking correctly is that what is written in the bible aren't gods words. It's gods words written down in humans words. You must not take it literally. For instance if in Exodus 21 23-25 it is written:

²³ But if there is serious injury, you are to take life for life, ²⁴ eye for eye, tooth for tooth, hand for hand, foot for foot, ²⁵ burn for burn, wound for wound, bruise for bruise.

This does not mean you need to really do this. You don't need to hit someone back if he hits you. You need to look at it in context. Back when this part of the bible was written, it was common that if someone came and killed one of your sheep, you'd go and kill all of his. It was revolutionary that you started to only kill one of his sheep. But nowadays, you wouldn't even kill one of his sheep. Times change, and you must read the bible regarding the context!
