Are Muslims pathological murderers who feel bad if they can�t kill someone?

you are quit alright, but that is not only about muslems, africans and japanese also have notorious background of invading and civil wars, but about the muslims the matter has been turned to be systematic! if you read islam's history muslim's always have been busy killing each other mostly with religiouse excuses, islamic grandiose easily declare other dissimilar muslims and non muslims as heretics and allow their folowers to do any kind of crimes against them! for example islam says: "and about heretics, kill their men and suns and capture their women and wealth in the allah's name"! this is just to choose who is heretic!
