Oh get bent.
The guy has to be a jerk on some level to have thought that what he did would be a good idea. Your average decent person doesn't suddenly get a bug up his ass to torment someone after all, and they certainly don't make such a display over it, even going so far as to UPLOAD IT TO THE FUCKING INTERNET! Get a clue. Or failing that, at least think before you run off at the mouth like that, going off in a misguided self-righteous tizzy.
Oh, and there's no need to be such a throbbing dickhead just because you don't agree with Harmony. Really.
They say that first impressions are everything, something that is pretty relevant here. Mine of you, is that you're a huge fucking asshole, and a rather large hypocrite to boot. Does that mean that I'm right? Having gone back and read the rest of your posts in this thread, it would seem that I am. You really are an asshole, and you're a rude, self-absorbed hypocrite to boot.
The point here, is that even if you suggest that basing one's opinon on first impressions is a bad idea, it's entirely reasonable to do so, especially when the circumstances come together to paint a pretty vivid picture. Much like how I'm likely right in believing you to be a self-righteous fucktard with his head up his ass, so too is Harmony right in believing that someone who would go to great lengths to humiliate his brother and then post it on the internet, is a big fucking jerk.
Now, as for you, having no basis on which build your opinions of Harmony, as he did nothing more than opine on something that's pretty black and white to anyone capable of a little insight, I believe that you can take those opinions, print them out onto heavy stock paper, roll them up into a tube, and then insert them into your asshole sideways. What you did here wasn't a case of extrapolating aspects of a person's personality through self-evident means. No, what you did here was attempt to pass judgment down on Harmony from your soap-box, believing that you had the moral upper-hand, and came off looking like a dickface with a chip on his likely hideously misshapen shoulders. Hopefully Quasimodo, you've learned a lesson here. Though if not, then I, being a man with a sense of tact so miniscule as to be non-existant, will be happy to explain it to you again, in less amiable terms.
Really though, you just ought to watch what you say to people, not knowing them at all as in this case. Something I believe you suggested Harmony do, though you lacked perspective into his particular opinion before having done it, and had you that perspective, might not have done at all. Which makes it all the more annoying that you'd do it, really. The more I think about the way you conducted yourself here, the more I want to see you stuffed into a sack and beaten with reeds.
The point is that the dude never needed to take it to that level in the first place. Pranks are all well and good, but when you post them on the internet for the sole purpose of humiliating someone, then you've stepped beyond sibling rivalry and made an asshole out of yourself.
Really, I fully agree with Harmony. The thought that people so often use the internet as a tool to humiliate others is rather disgusting. This particular case even more so, because the person involved perpetrated an act of cruelty on his younger brother, and then showcased it on the web to further humiliate him. It's disgusting, and the dude is an asshole for having done it.
