I don't know of another religious figure in history that out-did Jesus Christ in preaching forgiveness, love your enemies, and do not return violence with violence.
I am obviously biased; but, the Buddha places a high value on non-violence. In fact, the Buddha says that even if people were to hold you down and saw your arms and legs off, you should not let anger arise in your mind.
"Monks, even if bandits were to carve you up savagely, limb by limb, with a two-handled saw, he among you who let his heart get angered even at that would not be doing my bidding. Even then you should train yourselves: 'Our minds will be unaffected and we will say no evil words. We will remain sympathetic, with a mind of good will, and with no inner hate. We will keep pervading these people with an awareness imbued with good will and, beginning with them, we will keep pervading the all-encompassing world with an awareness imbued with good will — abundant, expansive, immeasurable, free from hostility, free from ill will.' That's how you should train yourselves.
"Monks, if you attend constantly to this admonition on the simile of the saw, do you see any aspects of speech, slight or gross, that you could not endure?"

The above link only gives an excerpt of the discourse. The very beginning is left out of this, the setup is that several monks had become angered over people insulting the Buddha. The Buddha wanted to make clear that no insult, even to Him, is worth becoming angry over. There is no religious justification for violence or murder.
