When you’re writing a character, don’t forget to make bad choices an option presented to them as a way to fulfill their desires. We as humans have to calculate risks all the time. Those in leadership positions have to calculate risks that may affect more than themselves. Those who aren’t in leadership still have to deal with the consequences of their choices and how they affect those around them. When your character realizes what they want, they should go through a series of options. They could scratch their itch one way which may seem easier and more accessible but ultimately leads to their own demise. Or they could scratch their itch in a way that lines up with their long-term goals and desires. This of course defines who is a hero verse who is the villain. Or just defines the turning point in which your character decides to take on the characteristics of a hero or a villain. Whatever they choose, they still remain on a journey. A path toward inner destruction is just as much of a journey as a path toward inner creation.
