The thing is, while this is a very good and likable Reed, it's also a reminder that Reed Richards is incredibly arrogant sometimes. It's not so much that he's egotistical, but here's a guy that got his friends mutated with his massive arrogance, and then, upon realizing what he'd done, he came up with a plan for how to fix it without really discussing the true nature of his plan with his loved ones, the ones affected the most.
Any time you see Reed Richards acting like a dick, you can argue "Reed wouldn't use that tone," or "Reed isn't that emotionally cold," or anything like that. But one thing I'm not sure you can ever say is "Reed Richards wouldn't do that because he's not that arrogant."
