If all you say is true, I'd shoot it again. I've done it with one of my wife bucks. I don't see that it violates any TX law or is even close to unethical.
Except it's after dark.
Back out and let the animal lay. if the shot was true he'll bleed out. Bump him out of his bed and you're bound to have you hands full finding him.
