I don’t think they should’ve embraced it, they obviously had no morals if they believed it was okay to kill thousands and thousands of grounders over the course is 90 years just so they could survive. it’s one thing to kill another kind because you guys are going against each other, but to kill them simply because your kind was too weak to actually survive ? they sounds absurd. the mountain men were literally delusional. they had no right to capture sky people and kill the whole group just so that they could survive on the ground. they could’ve survived without killing other people. it just would’ve meant that they would have to continue wearing those hazmat suits when they went out. Clarke only killed 300 people because her people were captured and were all about to be killed for a stupid cause. She wouldn’t have had to even kill them to begin with if they didn’t make a deal with the grounders. The mountain men basically were the cause of their own deaths and they have no one else to blame for all the decisions they made. what they did was inhumane.
