The whole plot of EX4 is developer's informational and mentall acrobatics to justify the idea "Geno is bad, Mercy is good *insert chad vs soyjack meme*".
If you compare circumstances of SHRIFT with game like Undertale, you will see how "mercy" ideas are different.
In Undertale, it was like "Yes, maybe monsters a little bit rude. Yes, you have all rights on self defence. But dude, they are harsh because they literally HAVE to be harsh. And yet, the most of monsters don't want to fight at all and will stop attack you after a conversation or another interaction through the battle. Characters like Asgore are even near mentall breakdown because of the sin's burden. So, you have power. You have your determination-thing. Maybe you will use it to broke this circle of violence? Maybe you will supress your urges and show some MERCY?"
In SHRIFT it is like "YOOOOOOO, WE HAVE KILLING MACHINES HERE!!! They killed sooooo many people!!!!! Like Archne!! Do you like our favourite edgy wannabe-predator???

Don't they? Sooooo... You are a good guy, don't you? What about some MERCY?
Huh? Are they going to change and stop killing people — you ask? You silly!! It's their nature ^_^!!!! Some of them even won't stop to try kill YOU
What do you mean "My common sense tells me that not ALL OF THEM are worthy for MERCY and i have an urge to commit genocide"? Why are you so mean ;(? I have that deep idea of pacifism and you are going to throw it out because you can't understand it? You stupid puppet of the Old One!!"
Undertale is about Mercy, SHRIFT is about pure Masochism. If you ignore information about world destruction and poor crying Kazuya, Genocide — is the best route. The only ones who i felt sorry about in Geno run were Lamplas, Empuse, Mother Rabbit, Hayakki and Echo.
Friendship and hentai scenes are temporary
But the Genocide is
ETERNAL
dunno if i should post it here or there but she's talking about MGQP, leading credence the the theory that you have to go through a NG+ to get the real ending there
