Notice how I don't advocate for attacking Russia - but granting Ukraine a decisive victory, where Russian forces are absolutely decimated and pushed out of the country entirely would hopefully make Russia think twice about attacking any other neighbours in that direction. If they are allowed to basically keep what they took already then it's the same as giving them a full victory - they generally don't care about loss of life, so if they keep the land taken it's the same as winning.
