Strewing together moral absolutes means you stop living in the real world. Violence and war brings more evil to the world, even if it is morally justified. Your failure to acknowledge any of this is appalling.
Somebody whose lost their entire extended family and village by mortar fire because the Ukrainians fought back will be in an objectively much worse position than under a harsh Russian occupation. Weapons, in this case, escalated the conflict and created evil for this person, no amount of moral whitewashing over "freedom" and "vanquishing the aggressor" absolves this.
It may very well be the case that the net utilitarian impact of Ukraine escalating their response to the invasion justifies the resistance, but we live in the real world, and nothing is as cut and dry as you claim, not even a hostile invasion by a despotic power.
