This multi-planetary species thing just won’t work. The most likely scenario is that we fail. However, if we succeed the species will split very quickly on account of Mars’ unique evolutionary environment. You would get earth humans and Mars humans, and knowing our nature as a peaceful species, I am pretty sure we’d wipe each other out in no time.
That wouldn’t happen for an extremely long time. It will be many generations before Mars would be self sufficient enough that they could wage war on Earth. I don’t feel like that’s enough of a possibility to not even try colonizing another planet.
