What Should I Do If I Become a Soul Gem?

To be a stone, it must look like a stone. Isn't it good to be a stone? There is no need to eat, drink, or work. When you wake up every day, you can look up at the sky and the scenery, and when you are bored, you can go to sleep. How wonderful.

If Thanos had the six Infinity Stones, who would control the stones? As a Soul Stone with a soul, you are already invincible and can borrow the energy of the entire universe. It's a joke.
