@Erato_Heti i feel the same in some ways, namely that there are a lot of worlds that have become insanely sanitized and speak-no-evil in an extremely toxic way . but i also can't help but look at your argument about speaking and smiling at the "evilthought" and see a slight similarity to "locker room talk" types of arguments that certain men make, and consider at the unique intensity of violence in the internet as well; my takeaway from these is that the "evilthought" is indeed evil and when shared has the potential to propagate.
i don't have a good answer to either of these issues. i think [the speaker's sanitizing everything and suppressing the void] and [proliferating the poster's violent speech] are sort of both toxic . honestly the truest answer is probably that things in moderation is good but i find that unsatisfying
