While being stronger than Nolan is possible, even when the main Nolan and Mark fought, it was clear that Nolan and Mark weren't trying to kill each other. In an alternate universe where Mark was actually trying to kill Nolan, but Nolan wasn't trying to kill Mark, then he might have won in a fight.

But then "murdered" might not really be the right choice of words. If he pretended to side with Nolan, then wait for him to lower his guard and then snap his neck, it'd actually be murder.
