Change the story. Find the missing link. Some characters are just spinoffs of a bigger story. Other characters are heroes in disguise.
Tragedies don't make a villain less than human. The same logic goes for heroes because flaws don't make them worthless. Perfection is just a tale we tell ourselves so we can convince ourselves that we are worthless and unlovable. Which is false. Why believe a false tale? Because we eat lies so often that we don't know that we are poisoning ourselves. ***** up the truths you think of. Color the black and white world in a rainbow for all that I care. Normal is bland and boring. Be weird, create own stories. Chances are you have people of all ages thinking for themselves without even trying. If they call you confusing, give a grin and show them a masterpiece.
