The best and most simple answer for those that wish to compare the brutality of religions such as Islam to that of Christianity and the Crusades. When a Christian lies in wait to murder, they are in violation of the message of Christ. When a Muslim lies in wait to murder, they are obeying the message of the Koran.
Anyone can claim to be killing in the name of Jesus, but if they do so, they are in direct opposition to the teachings of Christ Himself. Likewise and ironically, if a Muslim does not kill, tax, or convert the unbeliever for Allah, they are in direct opposition to the teachings of the Koran. For example, a suicide bomber is promised a direct entry into heaven if he murders unsuspecting innocent infidels—he commits no sin. In stark contrast, a supposed Christian murdering unbelievers is doing evil, according to Christ.
On another note, the first Viking Crusade (1096-1099) stopped the Muslim conquest and brutality in the Holy Lands. It was largely focused on returning the city of Jerusalem back to the Christians who had peaceful dominion in the city for over 450 years. The first crusade was defensive in nature. Christ makes it clear that Christians are allowed to defend themselves. What they are not allowed to do is lie in wait and murder innocent people.
There were a total of nine crusades. In contrast, there were over 500 jihadist battles against classical civilizations. Jihadists are still waging war and murdering innocent victims today. So when the supposed Christian crusaders made 8 or 9 offensive sins, they apparently either repented, understood the words of Christ, and changed their ways. Muslims, however, have always understood the words of Muhammad and they prove it with each murder, each battle, and every hate filled deed.
The message of Christ is one of change, forgiveness, and grace. Every single person has failed at being perfect. We all fall short of being the best we could be. But as we learn about how much God loved us, that he hung on a cross and died a humiliating painful death for us, we start to love others more. We begin to understand forgiveness a little better and practice it more often. Getting to know Jesus Christ changes how we see ourselves and how we see others.
