I'll admit, I was an awful Tama owner back when the originals came out. I was young and, after I was tired of taking care of them, my brother and I would have contests/experiments trying to kill them. We'd starve them, constantly punish them for no reason, overfeed characters to 99 lbs, never clean up their poo, neglect characters we hated, and then record how they "reacted" to being tortured in said ways. Not sure why we were so cruel to them...I guess once we were tired of actualy playing with them properly, we found new ways to amuse ourselves. At least we never actually destroyed the toys.
I haven't tortured Tamas since then, though. I know they're just pixels, but I get attached to them. Even if it's a character I don't like, I feel bad neglecting them, let alone deliberately torturing them. At least my new Tamas never had to suffer the way my old ones did. XD
