Guilt is an emotion which probably evolved for something like the purpose you describe. It is triggered by interpersonal interactions and is not under direct conscious control (it wouldn't do its job very well if it was). The OP's suggestion that guilt is something you 'should' feel in response to events outside of interpersonal interactions or your own direct actions is incoherent and reminiscent of the 'Catholic guilt' phenomenon. It appears that Catholicism found a way to train people to feel some kind of generalized guilt for all kinds of strange things beyond it's 'natural' application. This does not appear to be a helpful development.
