Thoughts about Shiro and Adam in the s7e1 spoilers:

Shiro was very sick and probably thought it was gonna be his last mission ever. However, when Shiro told Adam about going on the mission, Adam still asked how important HE is to Shiro. Despite Shiro telling him his dying wish, Adam didn’t honor it. I think that’s why some people view Adam as selfish; he didn’t let his significant other choose his last moments in life.

(It’s totally cool if you think it’s not selfish. We all love differently. Adam probably just wanted to spend time with Shiro till his last breath.)
