I don't want to be mean to you, but you do sound just like a typical NCR drone, right down to being angry and confused that you're left to think on your own.
BTW, if you know someone is rustling cattle, and they're big and mean unarmed combatants, why would you confront them instead of just turning them in? You can do that, at least in RP. That's on you if you do dumb shit that would get your ass kicked in real life, the game does a good job telegraphing what dialogue choices are good and which ones aren't(there is even a perk that literally color codes your dialogue choices if you're that clueless)
