"Canlarından can kopmuş"
?

"karanlık yollara sarpıp kirlenmeyi göze alacak mıdır"
I do not get the sarpıp in there?

Thank you.

Canlarından can kopmuş means a part of their souls broke off. That means they lived a very upssetting event and it hurted them a lot.

It is not sarpıp, it is sapıp. The verb is sapmak.
