Sinful human

Most people are quite selfish, irrespective of how aware of it they are, and most people also harshly judge themselves and the other particulars in their environment to see how much they can benefit their (usually quite selfish, though the ignorance/malice dichotomy is very present in practice, here) "interests", however beneficial those interests actually are for themselves or their acquaintances being irrelevant entirely. (An addict has his addiction in his interest, yet not his best interest, if such a thing could be defined at all.)
I find it interesting how people manipulate/control the medium of interaction/communication to either persuade, ostracize, or just plain identify. (Usually identifying for later predetermined ends.)
