I'm of the mind that any assistance that we can bring them, to "end their suffering," is a good thing. It's almost . . . merciful. 
I have NO inclination to bring an "end to their suffering", or to be merciful to these vile creatures...
I want them to suffer, to wallow in their self-induced pity party, for eternity!!!
The only instance I will consider being "merciful" would be in a situation with the DUmmie in Alexandria last week...
Even then, I would make them suffer as much as possible...

to every f'n one of you!!!
