This is me getting warmed up.
All the verses in the quran that advocates killing is talking about killing during a war, ALL of them. God punishing unbelievers has nothing to do with us. You will most likely burn in hell, it doesn't mean i will kill you, God is just warning you. So when you burn in hell after death, you don't say i didn't know. Also, we should avoid war in Islam, we should not start a war,
Quran 8:61
"And if they incline to peace, then incline to it [also] and rely upon Allah . Indeed, it is He who is the Hearing, the Knowing"
Stop taking a verse out of a whole sura and make up stuff. The way you talk just tells us that you never read the Quran.
Now, enjoy your book,
