What did Kafka want? (Metamorphosis)

Ive just read Kafka's Metamorphosis and (i will skip the review part.)

Kafka clearly criticizes the roles of the society, capitalism, but we cannot understand that as pro-communism either i guess. Because the roles still exist and the only difference is the gain.

I believe Kafka wanted something different, different from both of those systems' roles but i do not know, what?
