I think this is an excellent question. People often forget about threats to families/friends, and only consider their own lives.
It's of course very context-dependent and I'm sure different people have different beliefs. For example, if your friends and families are ardently against the government and would be willing to risk a lot, and you are having an impact, you might just ignore the threats.
And in a way I think if more people think like that, it's best, as that makes blackmail to friends/family worthless.
In most other scenarios, I would give them one chance. After all there is other good that can be done in this world. However, if they show that they can't be trusted. I'd consider that I have nothing left to lose, and go hard.
You all are forgetting that cats live on this planet too!
I mean, kinda hard to say without context. Are these aliens even compassionate? How smart are they and what's the reason for blowing it up? etc.
If I can't argue how fucking stupid it is to destroy the entire planet, I might become a fervent earth-destroying zealot and undermine their efforts through my utter incompetence.
The colours and a lot of aspects fit, but I find the expression of the face, with the hands pressed against the head goes in a completely different direction with what looks like panic or despair.
