Couldn't Adam and Hoffman go away from their chains?

I think it's the whole thing that they didn't want to.

Adam yes because the toilet lid was broke he could have used that the same way eric Mathews did. Hoffman didn't have that chance because dr Gordon threw the saw out of the bathroom out of reach of Hoffman so he was left to die in the bathroom but there leaves one প্রশ্ন is Hoffman alive অথবা dead no one really knows.
