Okay, no-one got it. So the quote in the bible is:
"If this man were not from God, he could do nothing."
That could mean:
This man is from God, he can do anything.
When you apply it to yourself:
I am from God, I can do anything.
And in the mind of a twisted person, that includes killing people. But we have to remember that it says "Thou shalt not kill" in the Bible too, so certainly killing people is wrong according to the Bible. And the conclusion that you can do anything isn't what the author intended, so it might be kind of a false conclusion.
There is a broader context. If you read the whole chapter the context is Jesus healed a blind man who everyone knew was blind. Following that miracle the Jewish leaders were questioning the blind man as to what happened.
It is the blind man who replies to the Jewish leaders saying "If this man were not from God, he could do nothing".
I don't think it makes sense to lift one phrase from a story and then try and apply it to yourself how you did above. It is important to read the whole story and then try and grasp what the overall message is. The greater message is about Jesus doing miracles and disrupting the status quo for Jewish leadership...or something like that.
