Was it right of my little sister to sleep with my older sisters boyfriend in this situation?

long Story short I have three sisters. The oldest is 25 middle sis is 21 and the youngest is 18. My middle sister and little sister are extremely close. My older sister doesn’t really get along with either of them especially my middle sister. We’re at a rented lake house with some friends, it’s like a mini vacation. Everything was going well until my older sister walked in on my middle sister and her fiancé having sex. And apparently he didn’t notice she had walked in but my sister did, and she laughed and kept riding him. Everyone woke up when we heard my older sister and her fiancé screaming at each other. We are all shocked this literally happened last night. My little sister started laughing at her and said karma is a bitch. A year ago my little sister attempted suicide and was in fatal condition at the hospital for a week. No one knew why she did it and it was a miracle she lived. My middle sis was devastated about it. And I only recently found out she had attempted suicide when she found out her boyfriend and my older sister had been sexting each other. And the stuff they had said was apparently very disrespectful and hurtful. my middle sister is the attractive One so seducing my older sisters fiancé was easy I guess. She said she did it out of revenge. It’s reallg twisted right now and everyone is shocked. Wtf I literally do not know how to react. What’s your opinion

Yes

No

No ways

I can see why she didn’t

No. It still isn't right. It shows she has low character by lowering herself to that position of her sister's.
I get how hurtful it was of the eldest sister doing that with the other's boyfriend but two wrongs don't make a right.
As for you: stay out of it. They're behaving poorly and since they feel this hatred toward one another a time out is best. They can not speak to each other till they mature enough to be civil.

No it wasn't as she disrespected herself and her family. What your younger sister did sounds like a symptom of mental problems she may still be having and she may need family support and an eye kept on her.
Your older sister paid the price for what she did with her guilt over the consequences and the shame of your family finding out.
As for your older sister's fiancee he needs to be gone forever.

That's beyond messed up, but at least he knows what a skank his fiance is, and he's a fool if he marries her.

You have really fucked up sisters. No morals apply here.
