Criticism of Koran and categorizing violence as preached in Koran is correct. And its true that the personality of Jesus is violence-free like that of the Buddha. But the Bible is not free of violence - only the role of Jesus has been taken over by the Christian/Jewish God. After all, where did Koran get the idea of burning hell where humans will be roasted. And then again lets not forget Abraham who wanted to slaughter his own child. Hebrew prophets did get engaged in war and violence - e.g. David.
I just want to let you know what Abraham did was an allegiance to the Almighty. The Almighty was trying to test Abraham’s faith
