Accountabil-a-buddy

What does it mean to be accountable for your actions? If a small group of people start doing crack; you did not purchase the drugs nor provided the location for taking them; but... if you take it, doesn't it mean you are still doing it, doesn't that mean you're still responsible? If this hot guy totally puts the moves on you and you end up having sex drunk... even if he initiated it, you still participated. You're still accountable, aren't you?
