Millions of ordinary Ukrainians will suffer much, much more than a bit of cold if we start buying Russian gas/oil en mass again.

If my choice is between cold extremities and dead or oppressed Ukrainians, I'm going to just chuck on gloves and more socks.

Ending the war just so it can end now will do Jack shit, because it will start again in a few years when Putin has refilled his ammo stores and his barracks, and then more people will die, be tortured and get raped.
