[SPOILER] Season 4 Episode 8 “The Cousin of Death” discussion (Ruth’s Revenge)

I observed something while watching this show for the 3rd time in the past year. Did Ruth ever really care about Three? She plotted her revenge against Javi and in one scene you see Three telling Ruth over the phone, that Wyatt would hate this, just please come home. Why would she jeopardize her own life if she cared at all about three. She knew there would be repercussions from killing Javi. So did Ruth really ever care about Three? Thoughts?
