Eh, I guess I'm just one of those people that loves fooling around with the unknown.
I love using glithces, even ones that can damage my game(Darkrai and Sheimi anyone?). I love exploring them, looking for more. Seriously, I must have used the surf through the E4 door glitch a ton of times in the past few days trying to figure out if I could go anywhere cool xD(nothing worked, except I did get to some area playing the Darkrai's music)
But yeah, glitches are a double edged sword. Some glitches can be good(Missingno), some can be damaging(again, Missingno). Some glitches have no benefits to the risk, such as some of the Harvest Moon Glitches, some have no down sides to it. It all is up to what kind of glitch it is if I dislike it or not.
