Can Muslims be trusted, with contradictory Koran parts ie:"Jihad kill infidels" predatory selfish intolerance?

All that is beautiful, in much of the Koran, becomes "invalid by paradox" because of the vague fanatically interpreted attack drone threads entwined within its teachings. Jesus and Mohammed could easily have or actually are best friends, according to the selfless all inclusive ideology they lived by, and yet, a "praise the lord and p the ammunition"/ "kill the infidels" seem to be the damaging aspects of opposite parallels of so called Christians and Muslims alike.
