AITA for "milking out" my grandfathers death?

Throwaway, just want to know if im TA

My grandfather passed away about a month ago. The whole process was really hard, I (19m) used to be really close with him when I first came from Korea to Canada. He would take me out and try to teach me english and take me to the movies in hopes I would be able to catch on to western culture and language. We used to have long talks about when he was in the Korean army during the Korean war.

This was all about 10 years ago, we stopped seeing him when his health deteriorated, I couldn't bring myself to see him. They told me he was no longer able to comprehend basic conversations, and would just ramble and ramble about his turmoil during his time in deployment during the war. No matter how many times my mom and grandma tried to force me to go, the closest I would get was to the doors of his care home before I would run back to the car.

As the years passed, my family stopped asking me and I never bothered to try and visit him.

fast forward to the present, I get a call from my mom that my grandfather was dying. Apparently, his carer didn't clean his diapers and he got a really bad infection. He couldn't recover, so he was just lying on his death bed awaiting the almighty.

I couldn't even recognize him, he was so small and fragile. They had to shake him to wake up, his eyes lit up when he saw me and instantly he started to cry. I couldn't believe I made myself stay away from him for so long, he talked to me about how he wished he could have helped me more growing up, and told me not to waste my life away running away, you only have one. In his will he gave me most of his savings, and his car that we used to take during our adventures.

We stayed until he passed. At the funeral, people I haven't seen in years were there. This was my first funeral ever, I was going to be standing by his casket during the funeral and giving a speech. I overheard people saying in Korean (Most people don't realize I speak Korean because my english is very good) that I didn't deserve to cry or be apart of his funeral.

During my speech I was tearing up and I literally heard someone say that I was crying crocodile tears, I thought of how my grandfather told me not to run and I stayed and finished my speech.

After the funeral I yelled at everyone who were talking behind my back in perfect korean, all of them were laughing at me and told me that I should be glad I was getting most of his savings and his car. There was this one and only white lady who was there who is your perfect definition of a karen, who yelled at me for making a scene at his funeral. She called me an asshole and to just sit and shut the fuck up because we were all in grief, I dont even think she knew my grandfather, but she was just there because it was open doors to anyone, she gave a speech as well.

I guess its fair that people don't think I deserve to be sad, but at the same time hes my grandfather, I will always love him. AITA?
