Nobody is googling "Murder" looking for a game engine and being disappointed that they can't find it. If you search "Murder Engine" this is the first thing that pops up.

I have an immediate family member that was brutally murdered. I also have no problem with the name of the engine. Of the things to take issue with, this seems silly. You would hate LOVE2D which has libraries famously named ANAL and LUBE.
