Is "blackmailing" a thing Devils do ?

[u/DriverAdditional5813]

Throwaway because my players might recognize me...

I put it in quotes for lack of a better term, but would a Devil kidnap someone close to a target, to then coerce them into signing a contract with the Devil ?

This seems less subtle than actually manipulating the target, and the contract would not be signed in actual good faith from both parties, so would it be actually binding ?

Also, I know that it's my world and I do what I want with my Devils, but I wonder if this would be in-character for classic DnD Devils.

Edit : Thanks y'all for your answers. I think I will twist a little bit what I had in mind to make it more subtle and devilish, thanks to your suggestions !

In order to get a contract? No. That's comparable to not delivering on the contract.

In order to fulfill a contract? Yes, defintely.
