You are probably brain-washed about the verse that calls for the Muslims to kill the Infidels. Right? Anyways, The Quran itself makes everything clear:
Anyone can be misleaded by just quoting a part of the entire sentence... "They killed him" draws sympathy for the killed person.
But the entire sentence proves us wrong " They killed him because he had murdered thousands"
Now that justifies the part... Similarly read the entire part. And if you do, you will find that the verse refers to the battlefield. In a war, if you find the 'infidels' who had tortured you and who want to kill you, kill them.
Who were this 'infidels'. If you read the entire context, you get to know that, these are those pagan barbaric people who had tortured muslims, looted their property, didnt even leave the old and handicapped tortured them too. And it was during this time, that ALLAH had commanded to be steadfast. These years passed with full persecution and not even a single muslim replied back with a Slap!
So, when they migrated to Madinah, it was revealed to them "fight for your rights" "If these pagans come to kill you, you can kill them too" As plain as that... Is this inhuman??? Any war general will say this.
But Almighty GOD, ALLAH wants more than this. What is it?
The verse continues, "But if the infidels want peace and want to surrender, ESCORT them to a place of safety"
The maximum a very merciful general will do is to say "Let them GO"
