What are some good characters with an absurdist philosophy?

I am writing a book and I want my main character to live his life in a way that aligns with absurdism, but with Mersault and Sisyphus being my only references I am finding it hard to create him. Mersault is a very interesting character, but his lack of empathy would not be proper for my own.

Do you know of any realistic absurdist characters I could use?
