I remember yesterday I was on /b/ and there was a thread where they were raising money for the guy to get prostetic legs, all the while posting tons of shopped images and bad puns.
If you dont like this kind of humor, thats perfectly understandable, but itd be best if you just avoided it in that case.
there is a difference between making jokes on a topic like that, and making jokes on a topic like this. now, i understand laughter is a natural thing, and who are we to really judge what somebody finds funny? at least, that's what i think. it's not really something that you can control.
now, there is something specifically about this incident that really makes it unfunny in my eyes: it's the fact that the bomb was specifically made to harm as many people as possible. yeah, that's pretty much every bomb's purpose, but instead of killing people, it literally ripped people to shreds and didn't kill them. now, this doesn't mean people still don't die every day in, let's say, vietnam. innocent people over there are blown to millions of bits every day by unactivated landmines placed by the us from the war. even after seeing the amount of people harmed by these things, if somebody made some kind of video recreation in a video game or something that was supposed to make fun of these incidents, who is to say i wouldn't laugh out of natural reaction? if something is funny to you, there isn't exactly a way to stop it from being funny...
innocent people will die all the time, i get if you try to find something funny in it, or laugh, because there is a certain humor in every thing, but try to keep it to yourself, because there will never always be people that agree and most of the time, people who make the jokes are just trying to get reactions. just like in today's world, people make tons of holocaust jokes, and a lot of people aren't offended, at least on the outside, by it (in my experience, no i don't make these kinds of jokes). this doesn't mean that it's ok, because i'm sure if you told this to an older jewish person who was alive during this time, or maybe somebody related to them, you wouldn't get the same response.
all people really want is some respect, but people tell jokes that are without mercy and it really kills people on the inside. humor is something that people are never careful with, and because of this, people are always doing things like killing themselves or hurting others.
