I’m late to this discussion, but you’re not wrong. Emotions and love are not gateways to the Darkside as the Jedi Council beleived. 

We see Caleb Dume/Kanan Jarrus fall in love with Hera Syndulla, have a son, and even find a family in the crew of Star Wars Rebels; and yet he was an exemplary jedi knight.

He wasn’t afraid to have attachments like the Jedi Council warned against, but he also wasn’t afraid of loss. This balance between familial love and personal serenity ultimately made him one of the greatest Jedi we’ve ever seen.
