I don't think Nate did anything wrong

Some of you think he was just a coward,someone tell me how was he a coward? Sam,Nate and Caleb are not Cops or Soldiers so what they were doing was very dangerous,yeah you got respect somebody like Sam for wanting risk everything to save the little girl,but none of them were trained to handle a situation like that. I doubt many of you would spend the day following a sexual predator that is armored and dangerous. Some of the things Sam did were very reckless like trying to confront the guy when they go off the road when he comes up to them and wanting to go see the girl too. Some of you say why did she not tell the people at the gas station about him,well we learn that he had all those guns in his house so he could have been armored and he had a bat in his car. They took a huge risk going into that guys house at night unarmed,it is great they rescued the little girl but ultimately it cost them their lives and Caleb got injured,if somebody is going to do something dangerous then they should really think things through or just let the police handle it(i know they were a pain in the ass in this movie). Honestly if they decided to head home they would not have any reason to feel guilty,it is the police's job not theirs like i said the police were a pain in the ass but they are the ones trained for stuff like this.
