So why did Michel ... [SPOILERS]

Something else:

When he hided in the woods and calls for Michel, it is only for ONE reason.

The reason is to feel secure!! ??????
He calls him to see if he is in the near. He kinda 'tricks' him.
If he does not answer back, he must be far away....he can be sure to go to his car or whatever without beeing attacted by Michell.

I agree with this post although, more than human loneliness, I think emotional shutdown is the central theme of the movie.

The movie is about a naive character (a bunch of naive characters when you include Henri and Eric) looking for a connection in all the wrong places - in this case, a cruising spot where people numb each other out emotionally for instant sexual gratification. According to the movie, the confrontation of those who are emotionally vulnerable and those who are emotionally numb fatalistically results in the first group's death. Henri dies. Eric, who wanted an exclusive connection with Michel, died. The inspector, who called out the emotional numbness of the people from the cruising spot, dies... and whether or not Franck, the most desperate character, will die, he's got the blood of his people on his hands.

Michel is the most emotionally numb character, which in movie language makes him the killer. Unlike many other secondary characters, he does not want to meet outside the cruising spot and sees it as a getaway from his normal life - that we know nothing of. People trying to bridge both worlds by establishing a connection with him causes him to shut them out, which in movie language means murder. Those who are emotionally shut down survive, and those who are emotionally vulnerable are shut down.

One could also posit that, by accepting three people's murder, Franck is on his way to shutting himself down completely in order to pursue his own personal obsession.

I think Henri sacrifices himself in order inspector realizes Michel is the Killer, because Franck was the main suspect so far. So it was a favour to both his friend and himself, to break free from loneliness.
I do also think Henri desired to be with Franck, but he would never really dare to ask, let alone to prompt the encounter; and it is very likely that Frack wouldn't agree either.
You know, life can be very boring; I myself live in a small quiet town, I go to the same coffe spot 3 or 4 times a week and to the same (straight but friendly) bar every friday, so maybe that's what happens in this place in the movie.
And well, I do as well know or have seen many gay men that come out to themselves and to the world as shallow sex hedonists (then complainning why nobody bothers to truly or deeply bothers to know and/or care about them), which is I think a good critique to the guild, but of course, not all of us are that way.

The ending made me think of abusive relationships.
In a straight setting it is mostly the woman who gets beaten up, ridiculed, raped and yet she stays with him. Because 'I love him' or because 'he needs me' or because 'deep down he is a good man'. The deeper motive perhaps is that she is afraid to be left alone.

Franck was falling in love with Michel, for god knows which reason. He didn't know him yet and after they'd met Michel did his best to keep Franck at a distance. Still Frank seems to 'love him'. In the end where Franck is calling Michel's name, he might have decided that Michal is 'a good man deep down and he needs me'. But the ulterior motive is not being left alone.
