I'm rewatching Kill La Kill and I've noticed that the word "kisama" is used by every one of the bad guys (Student Council, Satsuki Kiryuin, Ragyo, and so on) to address basically every good character (i.e. Ryuuko, Mako, her family, etc.).
I know that in the Japanese language there are multiple different ways to address another person depending on the level of familiarity you have with them and so on, and I know that "kisama" is the most impolite way of addressing anybody (and it's usually translated as "bastard" or something like that when it's used).
My question is: why does Satsuki Kiryuin use "kisama" to address the Elite Four? They should, at least, be worthy of a bit more of respect. Was it a stylistic choice that Satsuki would address virtually everyone (with few exceptions such as the butler and Iori, for example) in such a disrespectful way, or is there a different meaning for "kisama" I'm not aware of?
kisama
used to address people condescendingly or in conjunction with swear words and death threats, so it kinda became synonymous with "Hey, you bastard!" but the original meaning is lost on us since we haven't often seen it used otherwise.
