Without help from Mac2, Mark quickly thought it through. No time to hang around, thus a limit to what he could do about Tony's body. He had Tony's passport - pity he had to die, but he clearly had nobody special in his life anyway.
Even if he cleaned up Tony's face, he'd still have the body to dispose of. His priority was to get back to the villa quickly and hope the spooks hadn't gone round... but if they had, and discovered him gone, then the mock body in recliner was clearly a juvenile prank...
...particularly when he arrived back.

I love the way killers always seem to rationalize their heinous deeds.
