Nope. And Russia shouldn't get to keep what they've taken by force either. But it's not like we could give weapons to those palestinian children and they'd be able to turn this conflict around. That's an extreme example of this problem. Ofc Ukraine is much more developed, and has trained soldiers and stuff...
Anyway as I said before, the argument remains - are the west fueling a proxy war at Ukraine's expense, or are they helping them win? Maybe one day we'll find out.
