hihateus
A temporary period of abstaining from any and all positive or neutral emotions regarding one or more people, but instead feeling extremely unfavorably towards them.
Something like Darth Vader, Adolf Hitler started out his life on a fairly positive wholesome note and may have originally planned to only have a hihateus towards those humans whom he perceived as enemies, but his growing insanity and personal turmoil soon caused his incensed delusional despising of said factions to totally spiral out of control.
