Well, have a look in the old Testament then. There are very explicit rules about how to treat homosexuals and heretics for example and they are not nice.
(I like the brick testament - famous bible quotes illustrated with Lego stones)

And yes, there is also Jesus, but among other things he has (supposedly) said,
"Do not think that I have come to abolish the Law of Moses or the Prophets. I have not come to abolish them, but to fulfill them."

So it is really not that simple. But the basic comparison between Jesus and Muhammed, well the one seemed to be mostly a love preaching hippie and the other mainly a warlord. But I know I have met Muslims who were devout believers, but who would never use violence, except to defend themself.
