Actually, for me, I primarily dislike needless waste. A bunch of resources were dedicated to growing this orchard which will all go to naught. It's better to destroy the orchard than sink even more effort into it if it'll be wasted in the end but the lack of forethought and planning is concerning.

It's a bit awkwardly worded but unjust isn't the word I'd specifically choose, it was inherited from the OP so maybe their view of what "injustice" meant was different and I just hijacked it. Dunno. I interpreted is as an unjust allocation of resources that could have been put to more productive uses.

By that logic, all "injustice" is "I don't like it when X happens" - there is nothing more.
