russians are not foreigners, they are brothers with ukrainians. in fact many ukrainians are ethnically russians and most of their culture is russian adjacent. the concept of vengeance can only work if you're fighting against a foreign enemy, example palestinians against jews. the damage caused can be amended by russia but it will take time, generations of re-education, and effort of rebuilding. but most importantly, there will need to be a big propaganda campaign to convince ukrainians that they were fooled by the west to fight their brothers. when all these things are put in place, there's a good chance that they forgive russia.
