Crowds can be pretty bloodthirsty, but some can be real wimpy. Crowds range from the types who immediately all rush in to break you apart the instant the fight even starts, to the type that will actually encourage severe violence to be done to an obviously helpless/defenseless woman. In my 37 fights, I've experienced all kinds. Because of where I live and hang out, it's mostly the more bloodthirsty type I've had, but I've definitely experienced the whole range.
Out of my 36 wins I'd say that about 25 of them were in front of groups large enough to call crowds, and of those 25 crowds I'd say about 20 of them kept encouraging me to beat on my opponent even after it was obvious I'd beaten her and she clearly couldn't defend herself any more.
Then, the one fight I lost, that crowd was also really bloodthirsty. It was pretty fucked up. The bitch I was fighting had me down standing over me gripping my ankle and holding up my leg. I feel like she was pretty ready to just let it go at that point, but the crowd kept goading her and goading her until she put me in this lock and then wrenched hard as she fell back and sideways. It was fucked. She completely dislocated my knee and my hip. It was fucked up.
