If Adrian promises Slade the means to leaving the island so long as he does a few tasks for him I don't see why not, as it also means he gets to ruin Oliver's life even further.

Or Adrian could extort Slade with his son. I know the novels reveal that Slade's son Joe is dead but he has another son named Grant who does become Deathstroke later in 1x06. For Grant to be old enough to stage an uprising in 2031 he'd have to be born by now so chances are he was born sometime between 2008 and 2013 while Slade was plotting his revenge. That would make him no more than 9 years old at this point. If Adrian is going to use Oliver's son as levarage who says he can't use Slade's?
