Pain isn't handled explicitly very often in roleplaying games. There may be some abstracted mechanics that make you less efficient at fighting or whatever when wounded, but it's often not expressed as the effects of pain. Presumably this is because pain is unpleasant and many players would prefer not to think about it too explicitly.
So don't necessarily feel that it's a good idea to add house rules to simulate the effects of pain. While it may add some realism, it might also make the game less fun for many players.

Ohhh, more explosions; even better. Would it be too much to hope this sets off a slow chain reaction that will destroy the moon base in the next few comics? Probably, but I'm going to hope so anyway.
Really now, Pete. Losing out on a dozen mooks causes more pain than your character's father biting it? You're not even trying to take out Kylo Ren, who's a named enemy! Everyone knows enemies that have names are much more impressive to defeat than a bunch of nameless fodder. Nobody compares mook counts once boss counts are on the table.
I suppose this could be a way to try and tweak Kylo's nose. Pete does have this weird sometimes roleplaying/sometimes rollplaying thing that makes it hard to differentiate which he's doing at the time. That actually could be quite effective if Sally thinks Kylo actually cares about comparing Rey to himself.
GM: The remaining charges blow, devastating the near wall of the chamber.
[SFX]: Boom! Boom! Boom! Boom! Boom! Boom! Boom!
Kylo Ren: I look up.
GM: <roll> You feel the presence of the Force.
GM: You lock eyes with Finn and Rey on the platform.
Kylo Ren: Rey Solo. So, you witnessed the death of your father. Good.
Finn: Rey! Let’s go! This wall is going to collapse!
Kylo Ren: I bury my pain, stand, and walk towards them.
Rey: At least your pain can be buried. Mine is too raw.
Kylo Ren: Losing a father hurts. I know.
Rey: I could have scored a dozen troopers if that explosion hadn’t killed them!
