Yes, you could use destiny as a “excuse” for murder, and it’s true that given the conditions your were in when the murder was committed, you couldn’t have done otherwise.

However, that’s doesn’t mean the murder is justified. If you murder beCAUSE someone called you a dork, that’s not justified. The force you exerted did not match the force that was exerted on you.

In this case, you are likely a psychopath, so basically your brain is broken and you are like a rabid dog who must be removed from society.
