No it isn't a pity. It's called freedom.
The point is entirely this. If somebody can control your freedom, they can control you. Why stop at animals? Become a Communistic Dictatorship, where they control what color socks you wear, and how many breaths of air you take.
Your choice. Be free, or be a slave.
If the animal isn't yours, then don't treat it good or bad, until you get permission from the owner.
And about the animal's freedom? No one wants to be injured (including the animals). Those who are injured and can't scape from this reality don't have freedom!
You are showing a communist behavior with the animals! You control animal's freedom, so you control them! For these injured animals it's like to live in a junk communist/socialist house, where they aren't respected and treated as they should be.
The real choice humans can take here are: to be a communist enslaver or to be a decent person.
We are talking about lives, and lives don't belong to any man in this world.
An animal's freedom is up to its owner. Freeing an animal that was brought up in captivity, is just as dangerous to it as harming it while in captivity. But, it is up to its owner.
