[King Hadas]

I think I understand what you're saying, sort of like some immense Lovecraftian horror that once seen cannot be unseen. Personally, I like to think of Silent Hill as more like a phenomenon where a person's psychological disposition has a physical effect on the reality of the town. If a person with a good state of mind came to Silent Hill I imagine they'd find it very pleasant. Basically the town is just an unthinking psychological mirror of those inhabiting it. Everybody in Silent Hill 2 is self-hating so naturally they're treated poorly but notice they don't try to leave. Unlike other Silent Hill's there are no huge gaps in the road, James is free to leave but refuses to do so.

This interpretation breaks down with the other SH's but that's okay. I love all the Silent Hill's except for Homecoming (I haven't played Shattered Memories yet).
