One could argue that any kind of euthanizing is only humane in theory. Successfully euthanized subjects don't often give feedback.

Dun dun dun duuuun...

Get off the cart, another fade to black:

"You're gonna knock em dead at the veterans hall tonight."

you can usually see whatever it is have or not have pain while it's happening.

One should note there are plenty of methods that hide the pain completely. Take the stuff that killed Socrates for example.
