No comparison, Not even close. The Koran is full of commandments of violence for the Muslims in the present. Bible is full of stories of occurences in the past.
If you mean that to imply that Islam is inherently more violent than Christianity, think again. The Bible is full of stories of the past, but also instructions for the present and predictions for the future. I sample just a few here:
Anyone arrogant enough to reject the verdict of the judge or of the priest who represents the LORD your God must be put to death. Such evil must be purged from Israel. (Deuteronomy 17:12 NLT)
A man or a woman who acts as a medium or fortuneteller shall be put to death by stoning; they have no one but themselves to blame for their death. (Leviticus 20:27 NAB)
They entered into a covenant to seek the Lord, the God of their fathers, with all their heart and soul; and everyone who would not seek the Lord, the God of Israel, was to be put to death, whether small or great, whether man or woman. (2 Chronicles 15:12-13 NAB)
If your own full brother, or your son or daughter, or your beloved wife, or you intimate friend, entices you secretly to serve other gods, whom you and your fathers have not known, gods of any other nations, near at hand or far away, from one end of the earth to the other: do not yield to him or listen to him, nor look with pity upon him, to spare or shield him, but kill him. Your hand shall be the first raised to slay him; the rest of the people shall join in with you. You shall stone him to death, because he sought to lead you astray from the Lord, your God, who brought you out of the land of Egypt, that place of slavery. And all Israel, hearing of this, shall fear and never do such evil as this in your midst. (Deuteronomy 13:7-12 NAB)
"I will sweep away everything in all your land," says the LORD. "I will sweep away both people and animals alike. Even the birds of the air and the fish in the sea will die. I will reduce the wicked to heaps of rubble, along with the rest of humanity," says the LORD. "I will crush Judah and Jerusalem with my fist and destroy every last trace of their Baal worship. I will put an end to all the idolatrous priests, so that even the memory of them will disappear. For they go up to their roofs and bow to the sun, moon, and stars. They claim to follow the LORD, but then they worship Molech, too. So now I will destroy them! And I will destroy those who used to worship me but now no longer do. They no longer ask for the LORD's guidance or seek my blessings." (Zephaniah 1:2-6 NLT)
