means Being partly responsible for a wrongdoing because you helped, allowed, or stayed silent, even without striking the blow yourself.

from From French 'complicité,' rooted in Latin 'complicare' — 'to fold together.' A complice (the old word for accomplice) was someone whose fate got folded in with the wrongdoer's, their thread woven into the same guilty cloth. The 'com-' (together) plus 'plicare' (to fold) gives you the image directly: complicity is what happens when your actions get pleated into someone else's crime.
