Kate don't deserve to.... (Spoiler)
Survive! because she's a dumb slut, she is working as a professional tourist guide as i'm pretty sure so she knows and must be extra conscious for the responsibility on her shoulders to take care of her group lives in the first place.
From the start she shouldn't take them with her to a danger zone filled with deadly crocs.
First she must return her group to safety land because her duty in the job not their business to put them in the middle of it, then she can continue her work and respond to the call of her duty.
I can't live anymore without IMDb
