I think Terry Davis, and Ted Kaczynski were both similar types of guys that took different paths.

Both struggled mentally, one tried to prevent it, one accepted it for what it was.

I'm not saying Terry Davis committed suicide but it seems plausible given the situation, he unfortunately potentially had a delusional episode which told him to do so.

I'm not sure though but the ability to exceedingly think is a difficult one to live with.

But I suppose it's just as difficult to be an animalistic blissful creature, the fool doesn't know why life is bad, or perhaps that life is bad.

Whereas the intelligent are forced to carry the weight of their sins, and see the cruelty, and suffering in existence.
