Muhammad's life and story, his personage indicates unique wisdom.
Little too rapey and murdery though, don't you think?
You mean to insinuate that Muhammad (peace be upon him) committed rapes and murders. That is not the case. He waged many wars, because, like all prophets, he was severely fought without fighting back, for years. In the end God ordered him to fight back, it was enough turning the other cheek (13 years of harsh 7th century persecution without fighting back). Only then came the 9 years of fighting back. 13+9=22, accounting for the 22 years of revelation.
As to rape, this is not so. Before Muhammad spoke, girls were buried alive, just for being girls. If someone had a girl, he would bury her alive. But a boy was ok. This is how it was, as well as many other things. You don't tell these people to marry one wife only and to never ever divorce. This would be like speaking Chinese. Changes come step by step. So Muhammad (peace be upon him) ordered to not bury girls alive, to have great respect for girls and women, that a boy and a girl are the same, that greatness is in honouring one's wife, that divorce is allowed but most hated by God, that they could have up to 4 wives (though he still emphasizes to honour one's wife as ultimately as one can think of), that sexual intercourse with one's female servant is not adultery (people had servants and slaves at the time, male and female). Muslim women veil their hair. This means the hair of the woman is almost sacred, not to be shared with any eyes out there, just the husband and the family. This is what I think.
