'Deliberately' cruel? (Patreon)

I've asked around a bit for alternatives to [Cold-Blooded] as a perk name and Lazerus56 gave a suggestion that seems more accurate: [Merciless]

When I compared the definitions of the words, the most crucial difference was that cold-blooded is defined as someone who is 'deliberately' cruel, while merciless isn't that specified.

It should be evident that no matter how cold and calculating Rei becomes under the perk's effects, she's rarely if ever, shown any deliberate cruelty.

Hence, I'm fairly sure I'll change the name of the perk (it's going to be very annoying going through every chapter and editing them on my local files, P, RR, SH) lol

Anyway, I'd still like to hear your thoughts on the matter.

EDIT: I've decided to change [Cold-Blooded] to [Merciless]. I've edited C.7, C.8, C.10, C.14, C.16, C.19, C.20, C.21, C.22, C.23, C.24, C.26. Thanks for the input everyone!

Cheers,
