Many bad things on the Earth shouldn't of existed, no doubt about it. But sometimes, those crappy things lead to something great. For example, Transformers. Horrible movie that is a huge part of the bleak sequel, prequel, adaption filled mess that is the modern film landscape. However, that was the first thing the nostalgia critic ever reviewed, so without that we may never of gotten the nostalgia critic, bum reviews, Ask TGWTG, or anything on TGWTG.com. How about Halo? It basically set in stone many bad trends in gaming (five hours of length, putting the multiplayer first while cutting resources from the singleplayer, having every single game be about Space Marine), and has led to some of the most fowl mouthed 13 yearolds ever, but if Halo didn't exist, Red vs. Blue wouldn't either. What are other things you hate but are glad they exist?
