The stories in Ripples definitely painted the M&SU/Arcanists as a group of thugs (Nellie, Asami).
My view on Ramos, which might be incorrect, as I haven't read all of the stories: Ramos is an idealist, in so far as he thinks everyone should have access to magic. That is his end-game. He got inside soulstone mining and created the MS&U cause soulstone = magic, but he will sacrifice that on the Arcanist altar if it gets him closer to his end goal. He likes the Union, and the people involved, but they are just a stepping stone in a larger plan. I figure Ramos is his happiest when he can tinker in his own lab without being bothered, but that's too far away for now.
