[Rex doesn't like thinking about it either, and on most days, he doesn't.

He tries not to. When it comes to the actual "bad" guys, he can't say he feels too guilty. Most of the bonafide takeouts in his professional line of work involve the kind of creatures or people that would kill him point blank. The Flaxans had been vaporizing civilians in the street, slaughtering innocent non-combatants in droves, and had come back twice afterwards to only enact more damage.

Shinichi's question is one of the many reasons why Rex hates dealing with the general public. It highlights how deeply privileged they are, how lucky they must be, to have never had to make that kind of tough decision in the first place. For him it had begun with petty thievery, then murder, and now...

This.

But he too had asked the same question once. So for the first time during this entire conversation, he does his best to give Shinichi an honest, no-bullshit answer.]

You ever run into the kind of guy who'd kill a kid right in front of ya?

I know, I know!

[He throws both hands up in the air, palms wide in a grimly animated fashion. This dude is probably gonna have a shitton of bad dreams after this...

Rex hardly considers that his problem.]

Baby murder. The worst kind of murder there is! Probably. I... I dunno.

Anyway.

[The gloved hands are then carefully shoved into his pockets.]

People like me are the reason you haven't.
