Should Ukraine... just keep going?

Ukraine is making massive headway against Russia right now. Putin's forces are crumbling all over the front line. So my question is this.

Should Ukraine keep hammering Russia even after they have regained all of their territory?

Because all Putin will do is lick his wounds and rebuild. (if his own people haven't taken him out that is)

I'm not saying stepping onto Russian soil, but simply continue to destroy Russia's military until they're so broken they will never recover quickly. If at all.

What do you think?
