I don't know if this is a serious question, but it should be!

Was Jean Valjean unethical for stealing food when he was starving?

Was it unethical for the Allies to steal German scientists and secret research?

What exactly is the definition of theft? If the government authorizes me to 'steal' from you is it no longer theft?

If someone steals my cow, and I steal their goat, is it theft or retribution?

I could go on...

I brought that up earlier.

Thief? or resistance fighter?
Thief? or recovering your own stolen goods/or equivalent?
Thief? or vigilante?

To the nuts here and elsewhere the answer is YES! because their definition of thief is "everything on earth"
