Sans (genocide)

you enter judgement hall, after you walk a bit, you see a figure, standing in a badass away, he asks you if you think even the worse person can change, you take a step forward, he laughs, then he asks if you wanna have a bad time, you step forward, he chuckles again and says, sorry old lady, this is why I never make promises, you encounter, sans… the weakest enemy, or is he?
