Here's the thing. The Halloween series has different continuities. After Halloween 1 and 2, there are two alternate timelines, both of which follow the original 2:
 * Jamie's timeline: movies 4-6
 * The H20 timeline: H20 and Resurrection

So first of all, the single tear scene is only canon in Jamie's timeline.

Now here's the context: In Halloween 5, Michael sheds a tear when Jamie calls him "uncle". But then in Halloween 6, Michael kills her.

Also, in regards to Michael having enough characterization to be a CM, the CM cleanup thread on TV Tropes did discuss that.
