That character, with the distinctive face markings and confident, somewhat sinister smirk, is Ryomen Sukuna from the manga and anime series Jujutsu Kaisen.
The image specifically depicts a famous panel from the manga, where Sukuna (often in Yuji Itadori's body or in his true form) is looking pleased or amused by the chaos or suffering around him, fitting perfectly with the meme's caption about enjoying someone's downfall.
So, the original anime (and manga) is Jujutsu Kaisen.
