AITAH for not crying when my brother passed away?

My only brother recently passed away and understandably everyone in my family was quite upset. I loved my brother because he was my brother but he had a long history of substance abuse and sometimes was a tough person to be around. We had very little in common and I remember saying rhetorically to my wife when he was still alive, would I be friends with him if he wasn’t my brother? No. When we got the news that he passed away people were pretty inconsolable, but I never even so much teared up. I remember my wife telling me that it’s OK to cry and when my dad left to head back home he apologized because we never had an opportunity to have a good “cry” together. Sometimes I feel like a bad person or psychopath because I never expressed much emotion to the situation. I just picture him wherever it is we go thinking I’m an asshole. I don’t mean it to be like that.
