I removed a sense that I believe is not truly a distinct sense of the word but merely a figurative use of sense #1, i.e. "Dad is going to kill me," merely implying hyperbole that Dad is going to punish me severely, which I am dreading to the same extent--or which will be as painful--as if here were to actually cause me to die. I also removed "To force a company out of business" because I think that's just an extended use of other senses, i.e. to render something inoperative or to annihilate.--220.127.116.11 09:40, 8 June 2010 (UTC)
Might be a computing sense, but I don't know for sure. I vaguely remember the Visual Basic language from the 1990s having a Kill command that deleted files, and then there's the kill file. Equinox ◑ 21:09, 6 June 2012 (UTC)
