Amateur question: if we've retained these ostensibly dangerous or at least deleterious viral codes in our DNA, is there any reason why these virii don't serve a important evolutionary or remedial (maybe crisis) purpose?

Men who were prone to alternative/extreme states of consciousness would have been better able to summon up the wild emotions necessary for savagery and violence, making them better fighters and hence giving them better mating prospects.

Yet schizzos have fewer offspring.

It's likely analogous to scar tissue.

Ancient population suffers from massive viral load, causing such catastrophic damage that the whole surviving population carries some of the viral DNA fragments with it to this day.

Being alive is the reward.

somehow I doubt that someone with depression/bipolar disorder would be the best candidate to be a warrior

I dunno, a mania in the context of a major hunt or battle could really drive a tribe, I think, both in their mania and a lack of fear of death.

"You don't know" is damn straight.

Thinking mania can be controlled like an on-off switch.

Why even bother posting?

They would be constantly vigilant and unpredictable to someone unfamiliar with that particular trait. When wandering you might only have yourself as a reference so they would be a counter to that

> They would be constantly vigilant

If they've even lived long enough, no absolutely not. Unless you think someone who is routinely depressed is 'vigilant'.

[Hypo]mania is not the primary state of a bipolar patient. Can't speak to schizophrenia, but for those I've seen with that illness, functioning isn't their primary state, either.

A common evolutionarily explanation for the existence of depression in the case of an illness is that it forces the individual to take rest, and being withdrawn lowers the risk of transmitting an infection. How depression and inflammation are related is quite well documented.
