Considering that not putting the mask on had only made him increasingly more pissed off and more frustrated...? He hasn't been much of a happy camper.

"Doesn't seem like it, no. More I tried gettin' rid of it, the more it'd come back with this... I dunno. It felt weird. Like it got in my head." In spite of his best judgment, he wanted to put the mask on so badly.

Better to be stubborn and persistent than... whatever the hell would've happened to him if he hadn't resisted the siren call of nightmare fuel.
