Contrary to some not-so-authoritative officials, I don't find it peaceful, forgiving and kind, unless you are already a Muslim. Rather I find it accusatory and full of anger. That's my impression, having read it. Read and be you own judge.
Ever read the Old Testament, bud? Or, the Talmud? Even the devil can quote scripture for his own purposes.
The OT and Talmud are a must reading too. Too many things from there are not very compatible with the Christian way of thinking either.
However, the difference between the OT and the Koran are apples and oranges.
But why take my word for it? Let me give our less informed readers a "taste" of this (under the heading the Ultimatum):
[9:5] Once the Sacred Months are past, (and they refuse to make peace) you may kill the idol worshipers when you encounter them, punish them, and resist every move they make. If they repent and observe the Contact Prayers (Salat) and give the obligatory charity (Zakat), you shall let them go. GOD is Forgiver, Most Merciful.
[9:111] GOD has bought from the believers their lives and their money in exchange for Paradise. Thus, they fight in the cause of GOD, willing to kill and get killed. Such is His truthful pledge in the Torah, the Gospel, and the Quran - and who fulfills His pledge better than GOD? You shall rejoice in making such an exchange. This is the greatest triumph.
Gospel teaches to kill in the cause of God? Speaking of the devil...
