If Zelensky surrendered at the very outset, it would have avoided this particular bloody war, but what injustice would it have incurred for the Ukranian people? If Zelensky sued for peace terms and conceded territory 2 years ago instead of leaning into conscription, what harms does it risk for the Ukranian people and their long term security using Crimea as an example?

The answer to these questions is obvious given that whatever deal Ukraine ends up with is going to be strictly worse than it would've been at the start of the war. All Zelensky accomplished was to destroy his country, and to ensure that millions of people died or had their lives ruined to achieve a worse long term outcome for Ukraine.
