I can understand how you feel about all the wars and deaths caused by God or lead by God but also think about this. When or if you have or had children, I have three sons all grown now, you teach and raise your children in the manner that you seem fit, when your children do something bad, you punish them and sometimes the crime requires stringent punishment like a spanking or something alike. Why would God not have the right to do so with his children ? We are his children even Jesus said to be like the little children (innocent) Now God has many, many more children than we could ever imagine and God is very stern, just like we are as parents. True God gets away with killing people and we don't but then in the beginning we did'nt create ourselves.
Granted that these beliefs are for those who love the Christ and worship the creator, and that may not be fitting for you but then those who don't believe in a God really still cannot prove there is a God and the believe may not also, that is why there is faith, believing in something you cannot see. Anyway just my point of view, I felt compelled to write after reading your post...Have a good one !!!!
