Input: So, I sit at this table with two other guys in an class. One of them is depressed and possibly suicidal (lets call him “T”) and the other is edgy and dark  humored(lets call him “L”). L frequently jokes about serious topics like suicide and depression, with such enthusiasm that nearly the entire class can hear it, and have told him to stop several times (He doesn’t). He sits right across from T who is like I said depressed and maybe suicidal and sensitive , and T can hear everything L says. T doesn’t laugh at most of these jokes, but does not tell L to stop. I enjoy L’s humor and I frequently play along and laugh at it, sometimes to the point where I am unable to do work due to being preoccupied with laughing. An example of L’s humor is “Suicidal people are just (life’s) speed-runners”. I do try to get L to have a bit more discretion, especially when it is rather dark, but sometimes it is just too funny, and I know that I probably am an asshole, but I wanna make sure since I told this situation and that joke to my other friend (who has attempted suicide) , and he laughed at it, but he said that I would possibly have to take some form of burden in the case T ends himself in part to my involvement in L’s jokes, which is an undesirable effect for me.

AITA for playing along with L’s humor in the immediate presence of T?

playing along with jokes making light of suicide in the presence of suicidal people
