hello everyone wanted to know which demon they protect the criminals
I don’t know a specific demons for criminals, but I know that Hermes protects thieves so maybe he can help.
Valefor is the one you are looking for. He protects criminals and thieves. Especially the ones who belong to organised groups.
Also Belial as Lord of the Lawless, He protects the guys who are against the Law and the ones who fight the legal system.
Another suggestion or go to would be Lord Qayin the first murderer.
This tends to depend partially on whether you want success in an ill-advised criminal career or whether you are fighting against criminal charges. At least, I would assume that’s the difference.
According to V.K. Chernobog might also assist you.
