I think I’d lose the part about him being a scoundrel. After saying he’s a rogue it sounds redundant. People don’t use scoundrel much anymore either. Sounds too old-fashioned for this modern story.
Grammar Girl strikes: drug and induced should have a hyphen between them.

and without is one word :)
rogue is devious, a ninja, and mostly it means he operates alone, not affiliated with others, but scoundrel is mean and two faced and underhanded, they are not the same. I think you need both.
