When you put it on a tripod and used liveview, did you remember to block the eyepiece?  That can and will cause inconsistent results.

A really good way to check a lens for consistent focusing is to use FoCal Pro.  It sets the lens to infinity or to minimum distance before every shot (you set the options)

You can easily see if the lens is focusing consistently, or if user error might play a part.  There is little doubt that a damaged lens can focus inconsistently.

BTW, they all vary occasionally, but should be reasonable.
