9/10 Arthur Fleck - INFP
For INFPs, the present is always temporary, since they believe the future will better. INFPs also live by their own values and that's why Arthur (The Joker) appeared to be amoral. He didn't flinch when he killed the three men at the train station because he didn't feel it was wrong.

Bruce Wayne is a Scorpio zodiac sign, which belongs to the Water element of astrology, along with Pisces and Cancer. The symbol of Scorpio is a scorpion, which represents intensity. As a Scorpio zodiac sign, Bruce throws himself passionately into everything he does.
