They are blind, the dwemer tortured them for years, they don't know or understand anything from the surface... Look at it this way, they're like that guy who goes to jail cause he murdered someone on a PTS flashback. Their whole race was almost exterminated by the nords, they ran to the dwemer for help, the dwemer blinded and enslaved them, and worse, people go through their caves slaughtering them mercilessly who they cannot see or understand... How are they to know humans aren't just monsters from the suface world who are invading their homes to kill their familes? How many falmers have come home from a long day of sqrounging for the scraps of food they survive on, and found his whole village slaughtered and everyone he knows dead, and their is a group of things, which he cannot see, picking through the wreckage of his village... what would you do? They were driven to the deepest, darkest, most inhospitable depth of the world, and when they try and build their homes there unseen mosters run through and slaughter them all. One of most tragic thing about them is that the dwemer not only took their sight, they took their whole history. The saddest thing is that the only ones who could have communicated with they slaughtered while under the control of a mad vampire preist dude(chanty of Anuil-El. They have just been screwed by the world, so their hatred is explainable. THEY KNOW NOT WHAT WE ARE! They are blind, an their weapons are crude, so of course they fight dirty. Also, the children backstory makes me sad you can only adopt two children. sorry for the LONG post, people tend not to feel empathy for the falmer. And who is Meeko? I do not know what you guys are talking about.
I know what you mean about the children, I usually adopt Sofie and Lucia, but I wish I could adopt Blaise and Alesan too. I feel really bad for them since they are basically street kids, Blaise and Alesan have 'jobs' so I feel worse for Sophie and Lucia who depend on the kindness of other people to survive.
