The argument I made was that non-existence is preferable ( to me that SEEMS wrong but I logically can't disprove it and I have tried). But that doesn't mean it is justified to kill someone else in the same way it's not justified to force people to eat healthy food or avoid using harmful drugs. Also when I said non-existence I really meant pre-life rather than post-life because once you are in the world it's not easy to decide to leave.I have no problem with the comment you made and it was pretty funny but in the future at least follow it up with an argument.
