A hypothetical discussion about vengeance

In a scenario that either Nick or Judy died at the weather wall. would the surviving member kill pawbert in cold blood without remorse to avenge their partner.

In my humble opinion: I could see Nick completely losing it (one he confirmed she was dead) and ripping pawbert to shreds on the spot.

As for Judy I could see her finding the venom pen and stabbing pawbert and sit there and watch him struggle and die.

But what's your thoughts?
