In the bible god kills many, orders for children and animals to be killed, apolitical creatures. Why?

When I ask about this people tell me that those were different times and that we are no one to judge god and his actions, that we should just obey and never question. They say that since god gives life he can also take it away at will.

I'm sorry, this is unacceptable and I don't care if people think I'm arrogant because I will not worship someone who thinks killing children under certain circumstances is okay.

I'm not concerned with god because I know the biblical god doesn't exist, what really concerns me is the amount of people willing to ignore murder to gain a place in heaven or avoid a place in hell.
