Not intentionally.

Leaving a defeated enemy lying unconsiously in the forrst (something they did during the Oracion Seis arc) might very well end up with them being eaten by animals for example.

And if Natsu knocks f-Rogue out and he falls of Motherglares back, I doubt Natsu'll dive after him to make sure f-Rogue doesn't break his neck on hitting the ground.
