The most horrible character? Reimu. For soooo much reasons. Greed, selfishness, power hunger, party-ruining, all this under the sake of her title of shrine maiden, she has attacked a vampire who just wanted less sun, attacked ghosts who wanted more winter, rampaged aliens for wanting more moon, kicked the fuck out of legal services members because they wanted more flowers, (Insert gruesome synonyms) the hell out of GODDESSES because OMG ANOTHER SHRINE MAIDEN, CONFLICT, annihilated a nuclear danger for being a nuclear danger, and willingfully attacked ANOTHER GODDESS for "OH SHIT TREASURE SHIP MIGHT HELP FOR DONATIONS".
Ahem~
Greedy and selfish... Maybe a little. She's only human. Power hungry? Where do you get that from?
If Remi had succeeded, there would be NO SUNLIGHT, which would kill the ecosystem of Gensokyo and eventually lead to the death of everything that wasn't already dead to begin with. If the eternal winter HAD been eternal, then pretty much the same thing would have happened.
The Lunarian exiles STOLE THE MOON. Seriously, wouldn't anyone think this was a bad thing?
The flowers were the SOULS OF THE DEAD. They were only there because the process of life and death had been interrupted. Had they stayed there, then whatever would've happened would likely have been very bad indeed.
The Moriyas were trying to pressure her to work for them instead. Obviously she would've felt a bit insecure about this.
"Annihilated a nuclear danger for being a nuclear danger". Stop and re-read what you wrote for a moment. Isn't this a GOOD THING?
Byakuren isn't a goddess. Nor is she Jesus, as so many people will claim. Ahem. And y'know, that wasn't the reason she was after the ship anyway, so...
I think you need to rethink your evaluation~
EDIT: Alright, I realise I
may have been a little harsh here. Sorry about that. Just trying to make it a little less subjective, I suppose...
