Condemned to Exile
As a child, there are asked many things you don't dare to think twice about, like your favourite colour, sweet, parent (or guardian), most of the times you're laughed at or encouraged to love and follow through with them...
...then there's what you aspire to be, your dreams, goal and desire, but when you suggest things such as superheroes you're corrected to doctors or firefighters, they do save lives in a sense but that's not what you said, that's not what Midoriya said.
But he never wanted to give up on his goal. No matter what. He may have been clever, but naivety and his persistence overtook his body and so he didn't listen to the truth around him, but when hearing it from the man he admired that's when he realised that people really can't always be what they dream to be.
An AU in which Deku takes an alternative pathway. The villain path.
