Heard this phrase on two different programmes this week.
Zoe Tapper who plays Ellen Love in Mr Selfridge has been interviewed on two shows and they have talked about her character Ellen "leading Mr Selfridge astray" even though (and i know its a tv show) a. hes cheated on his wife before. b. it implies that he isnt responsible for his own behaviour.
This is just one example.
Ive heard this phrase used to describe situations in RL too. It grates.
