More or less, Micheal was describe by John Carpenter as "living Evil" hence why he can't die, to evil death is just an inconvient set back. He kills, simply cause he enjoys killing, he has no motive, no reason or anything.

As for the tear scene, I believe it was stated the idea was they wanted to suggest that underneath it all perhaps there is still one part of him that isn't consumed by evil.

Although there is a fan theory, that its more or less the same reason as why he only kills when wearing a mask (as he's really got no need to hide his identity) and why in the first film he actually stopped trying to kill Laurie until he put his mask back on. Simply, he hates his face, it looks to different from who he truly is inside.
