Think tactically.
If these people are willing to come over and join the normals, welcome them.
Fuck your vengeance. Shove it up your ass. I get it, it's not wrong, but under no circumstances does a participating member of a team doing critically important work turn down legitimate help (if that's actually what it is) over it.
I'm sure it's a good idea some times and not others. No turning down genuine assistance, and no failing to recognize genuine assistance because you're angry.
