Somethings that are reasonable to you aren't to others, and vice versa. So....your point is.....
Have you thought about the fact(assuming there is a GOD) that god in all his/her/its glory/intelligence/experiance is so advanced a being that he/she/it transcends the human values we hold as being good and bad completely?
What I mean is that if there is such a being as GOD, don't you think he would have a completely different thought pattern and perspective than us, one so advanced that we wouldn't even be able to comprehend it at all. Just as how our thoughts and mental processes are dependant upon certain variables, I would think an all powerful being who has been around literally forever would be laughing at our pathetic attempts to rationalize his/her/its goals and thoughts.
The fact is that human beings are extremely illogical, unrational, weak, and undeveloped. I think we are at just the beginning of our history and have a long way to go to being advanced life forms.
