Did not know Opiumud is a woman, anyway, the only thing in which BOTTR is more extreme than some Opiumud files, is the gore at the end if one uses that version (but is gore with a dream, or maybe premonition ;-) to "clean it up") and the scene when one of the mosters sticks the hammer in her , which is part of the same.
The bruises are more visible (red marks) in DL, but even in Opiumud there is beating ( I think the "tecnical" term is ryona, or something like that), and on the other end, putting aside the mosters and devils present in both cases, Opiumud has even bestiality in at least one from long before, that DL is only putting the now in the Rey video (rancors).
Think how far a mother can do to protect her children, than convert that dedication and love in hate and destruction, that is how far a woman can go - luckily women go on the aggressive less easily than men, and in priority they do it intellectually and emotionally, with gossip, etc., are less prone to the physical violence (though psychological can actually leave deep scars and ruin people's life as well, in general more than just getting a punch).
Fantasizing about a violent punishment, can be a way to release that energy without actually hurting anybody, which means, it is perfectly possible for a woman to spend hours on it (without forgetting, if she is getting a good living income from it, it is like a job, she may not like some parts of it, but it pays the bills
).I prefer myself to always expect people to be nice, and woman the gentle sex, but that does not mean that one must not understand and recognise the possibility that things go differently - life and people are more complex than a fixed image.
