The biggest problem of these artificial environments is the threat of sabotage from either disgruntled, suicidal or criminal minds.

You can vet people as much as you want but with the pop they are talking about someone’s bound to go crazy or be an agent of discontent. And then if they are settlers of course their children can be as varied as they are on Earth, which means the possibility of the same.

I don't see where criminal fits in aside from the fact that a sabotage of that sort would rightfully be hideously illegal. What is to gain personally from that destruction?

It might be a pedantic quibble but I can see power as the only "rational" sabotage motive. Which could include some disgruntlement. Either to oust management or rivals to gain control or possibly international politics where one thinks they can gain from the loss of the colony for the sake of their earth nation.

Suicidal can be taken as granted to be irrational and disgruntled relatedly as "so fed up they want to see everything collapse to make them suffer".

Imagine beeing sentenced to a desert prison, by your parents, a monastry of eternal work and little fun, where all the beauty of world, is that coming from another world, as videos, games and mail, which you can never reach.

> What is to gain personally from that destruction?

The promise of a ticket back to Earth and a shitload of money.

Maybe a part of the mission is to design a society to minimize or eliminate violence, mental illness, crime, etc. What would a society look like that depends on near-perfect harmony and peace for its very survival?

[Mirioron]

I would argue that it would be a dead society. It just takes one person who feels that being hurt themselves is worth it just to hurt others for whatever reason.
