It added to my learning by boiling concepts down. Utilitarianism focuses on results rather than intent, and the ideal end result is happiness. Therefore the desire for happiness underlies any want we want or action we decide to take, and therefore drives our morality.

Hume believed that human morals were highly rooted in emotion and sentiment, such that experiences colored future views with associative emotions. These develop into morals that are based on emotion and driven by reason. This aligned with Empiricism, and what I assumed moral development was.

Kant, however, believed in the following of absolute rules with no exceptions. And it was his view that "good lies" were impossible, that asked me to think in new ways. This Rationalism argues that morals are based in reason and that we are born with a set of them that is certain. Because of this, Kant believed that if someone lies to help another person and six or seven iterations down the line, someone dies, the original lie teller is responsible for that death. This made me question any action I'd ever taken that I thought was helping.
