GM: You see a beggar in the snow, what do you do?

CN: I plink him in the face with copper pieces while making fun of him.

GM: Dafuq?

CN: Then when I run out of money I grab him and say "okay, it's your turn, let's switch places!"

GM: He freaks out and runs away.

CN: I chase him, sword out, and shout "Come back and be my friend you little broke bitch!"

i had a chaotic neutral player once that was trying to convince a lawful evil player that it was wrong to kill a goblin when they both work for some guys who were telling them to kill goblins

LE player remembered CN of his alignment and he intantly killed the goblin

Would it be out of character for a chaotic neutral person to just help someone out on a whim?

As long as they don't go from a broken begger voice to an aristocratic voice in half a sentence because of a shit voice acting budget.

Sneeze on hanky. Give begger hanky.
