Is severe drunkeness and a large group of drunk people cheering you on a real excuse for screwing around?

I don’t want to give too much detail because this is a story of someone my husband once worked for while in the military.
Guy (let call him Adam)
Adam recently married left for his first deployment. Went out with a bunch of guys and had way too many drinks. The bar was on a beach side. All of them where really drunk.
A girl (lets call her mrs slut)
Mrs. Slut also married had the hots for the guy and one thing led to another with body shots ending with sex on the beach with him and several other guys. Everyone cheering them on.
Some of the guys blame Adam situation on his being stupid drunk. And other guys egging him on.
Of course all us wives said he wouldn’t have done it unless he wanted too, drunk or sober.

I know when I was single, I got really drunk once and a guy who was always chasing me tried to kiss me.
It sobered me up real quick and I told him the only chance he would have with me is after I’m dead.
So my question is, Can a person who is severely drunk and goaded by others, do something they would never dream of otherwise doing?
