<human>: Can you succinctly summarize the text in 1-3 sentences?

Recently discovered this subreddit and decided to submit a fuck up that will haunt me for years. Made a throwaway just for this.

In my junior year in high school, we had this classmate who we liked to pick on - I'll call him Remy just for the sake of clarity. Although he was friends with all the guys in our class, we enjoyed picking fun at him and he never got pissed off at us, so it was all some good, friendly banter among us.

One day, one of the dudes in our class decides to try and pull on Remy's hair. A good few strands came off, but not too much to alarm us. I join in on the fun and pull a bit of his hair out, too, and one of the guys makes a joke saying that he might have cancer. It became a regular thing after that, pulling out his hair and suggesting he had cancer.

Fast forward to around three years later, and I get a text from one of our mutual friends. Remy's in the hospital after doctors discovered a large tumor in his head. I'm told Remy already has Stage 4 cancer, and the tumor was there for a few good years but wasn't found until that time.

I'm hoping it's a cruel joke, but word gets around to people from our school that he indeed does have cancer and his health is going downhill at a fast rate. Some benefit events get organized to support him too, and our mutual friend gives me updates all the time about how his health is doing. Remy eventually comes to a point where he doesn't know some of his friends and stays in the hospital for an extended amount of time. I never got to see him during this time though.

Fast forward a few months more, and he finally succumbs to it. I go to his wake, and the first time I see him in years is when he's dead after battling cancer.

Felt a little bad, and some people joked that he died because my classmates and I made fun of him. I know it's not my fault that he had cancer, I don't blame myself for that, but I wish I knew better than to make a joke like that.
<bot>: Pulled classmate's hair out, made a joke about him having cancer, classmate actually does have cancer and dies from it a few years later.
