Do people who’ve endured extreme trauma ever deserve a mercy killing?

I feel like for people who've suffered a spinal cord injury, their pain is physical.

For those that suffered a lot of trauma it's more a mental death etc.

Can't compare the two. I would imagine spinal cord injury is much worse.

But I'm curious if people underestimate how lifeless it can be living with extreme trauma.
