What would they need to feel remorseful about? Automating a video game? It's not like they're breaking the law... I think bots are the least harmful type of cheats anyway. I remember my first intro to programming was modifying Action Replay codes for online NDS games, that was fun but I ruined many people's games doing so. I do kind of regret abusing it like that in hindsight but I would do it again given how formative the experience was.
