Nigger it's a third choice.
How about fuck you both, kill you both, this is our fucking planet and you can get the fuck out.
I like choosing my own fucking life and I like not stepping in blood every 5 seconds.
It's more a "how about fuck both of you, we're kicking your moochy asses off the earth" choice
SMT 1 involved killing both parties so you can rebuild the earth,
SMT 2 involved doing the same goddamned thing,
SMT 3 was about basically paying all sides a visit and telling them to fuck off and you get to keep your cool ass demon powers
and SMT 4 was about getting this cool old fuck spirit dude to get his ass and his Kamen Rider peeps back in gear because everything went to shit, while also killing both parties.
If you're such a pussy bitch that you're bowing to some arrogant fucks because you think they have something to offer, then you're just some sycophantic pussy who can't carve his own path.
I mean, fuck, the original hero's outfit is fucking green, the color of Neutrality, which doesn't mean indecisiveness because Law, Chaos and Neutral line up with D&D sensibilities.
If you're Law, you're a fag who adheres to the laws even if those laws come from a shitty culture, if you're Chaos you basically shit around and piss on the king to create chaos or just start shit for the hell of it, but if you're neutral, you're not only out for yourself, but you're out to fulfill a goal, be it getting a fucking cookie or saving the human race.
This is what neutrality means in this game, to make your own path and not give a fuck about those impedeing it.
Be an individual or be subserviant.
The best and hardest ending, the one with the most bosses and playtime should tell you they are rewarding you for choosing to carve your own path.
