No other Holy book instructs so much violence on its adherents! Jihad is only one example. Killing non believers who will not convert under force. Men are also allowed, sanctioned by the Quran, to beat their wives if they disobey.
The Quran:
Quran (2:191-193) - "And slay them wherever ye find them, and drive them out of the places whence they drove you out, for persecution [of Muslims] is worse than slaughter [of non-believers]... but if they desist, then lo! Allah is forgiving and merciful. And fight them until persecution is no more, and religion is for Allah."
There are Shabads in Gurbani which 'wish' that evil people were not born. It doesn't mean we go out and kill them. Sometimes people take things too literally.
