Never mind the ethics of it... The majority of us posting here will have been with someone who was 'taken', at some time in our lives.
Maybe even multiple times...
I'd be more concerned about personal safety.
As I said in an earlier post - When I was younger, I was in the situation where I almost came face-to-face with a husband carrying a potential weapon.

And I know that younger guys feel as if they're indestructible... we've all been there in our youth.
However - If you get caught.... you might get away with it - or you might get hurt - or you might end up in hospital - you might end up permanently disabled - or in the most extreme case you might even end up in a coffin.
I'm not gonna tell you not to do it - I've done it myself.
But if you do.... BE CAREFUL!!!!

edited to add:
I'll relate my experience, and a few basic details because it just shows how easy it is to be caught out.
This was in the 'Redhall' area of Darlington, England - Wimbledon Close to be exact, one of the 5 houses facing onto Coombe Drive (Look it up on Streetview if ya like)
Like I said earlier, I was 19 and she was 29, we'd met in a nightclub and it went on for about 3 months.
She told me right from the start what she was up to, I know I wasn't the first, and almost certainly not the last. There was no involvement apart from the sex, which was a regular Friday night thing when her husband was out to playing in a local Pool league.
This happened in the early 80s, long before mobile phones existed so we had a signal organised to indicate the coast was clear - She had a vase of flowers in her front window which you could see as you approached the house, with a flower pattern on one side of the vase - If the pattern was facing outwards it meant her hubby was out - facing in, and he hadn't gone out yet.
The night we almost got caught - She'd turned the vase after he went out, but he'd come back because he'd forgotten his wallet or something. As I walked up towards her house... I was maybe half a dozen paces from the garden gate when the front door opened and he walked out...
I just walked straight past, but I could see her standing behind him with a shocked look on her face
. I did go back after a short wait, she told me why he'd come back and that he'd be out late due to a tournament he was in... so we did the usual (I was young and keen - LOL) But after a few days to think about what might have happened, I never went back again. At the age of 19 I had no desire to be confronted by an angry 30 yr-old carrying a Pool-cue.....
