Input: So long story short.

A dude from my grade decided last year that he wanted to be a rich artist. His qoal from the start was to earn a lot of money, at least that's how he talks about it in interviews.
During this year he has gotten a lot of exposure, he is working together with our parish and earning a respectable amount of money for a high schooler. I believe that recently he even got his own art show at another city and has held multiple ones here where he lives. 

Then I discovered something. All of his art work looks heavily inspired by an artist named Basquiat. So heavily, that when I showed pictures to my friends, they all immediately saw similarities.  (For an example the dude from my school paints the exact same faces and adds words, just like Basquiat does, only my acquaintance doesn't write them out completely. Even the colours are mostly same)
Now the dude is kind of an ass also, he thinks he is better than everyone and pretends to be this serious artist. After he started earning money from his paintings his ego went through the roof and most people would agree. 

So I've been doing silent exposing already, showing Basquiat's works to my friends and making them aware, but I could do more.
Our school has a popular account on Instagram that over half of the students follow and it only posts memes of our school, a way to vent our frustrations. Nobody knows who runs it, but it's secretly me and my friend. 
My friend after hearing about this had an idea to post about it on our page, but I argued against it. Yes, the dude is a douche. Yes, the things he does are wrong. But, I don't want to make him feel like shit. 
It feels to me like it is morally wrong to expose someone like that, especially because the dude himself has a lot of problems with his family and in his personal life.

So, Reddit, would I be the asshole if I exposed him for plagiarizing a famous artist's work?
