It sounds like a Stoic tactic, similar to negative visualisation or 'premeditatio malorum'. The way you approach it as a reasoned tactic to produce a specific effect, suggests to me their methods will chime with you. They use tactics like meditating on your death, to approach life more fully, and realistically.
Christian thought sees humans as corrupted & sinful, only able to overcome that through divine intervention. Gnostic thought goes even further, picturing the material and temporal circumstances as ruled by evil powers, and salvation as only possible by reconciling with that fact - it has been popular in times of chaotic wars and epidemics, and historian Niall Ferguson describes it as the 'original conspiracy theory'.
Rousseau saw 'civilisation' as a backwards step: "our souls have become corrupted to the extent that our sciences and our arts have advanced towards perfection". And philosophical pessimism generally sees the human situation as problematic or unsalvagable, typically advocating self-denial and some measure of seperation from society.
Antenatalists like Benatar follow this line of thought to suggest coming to be is a net negative, a net cause of suffering, so it is immoral to reproduce.
