AITAH for not helping my best friend's father clean his old room, years after he had passed? (mention of sh)

This is a community like r/AmITheAsshole, except unlike that subreddit you can post interpersonal conflicts. Anything that's AITA including relationships, hypotheticals, even posting about Scar from the Lion King and trying to convince redditors that he was not the AH. AI scenarios/posts are not welcome or tolerated. An elaboration on our rules can be found here: https://www.reddit.com/r/AITAH/wiki/index
