Capitalization in a text has been something heavily debated in the writing community due to its nature as being preference based, and finding a hard set answer is fairly difficult. However, should capitalization be used for emphasis as part of a character's tone?
Assume a character is based purely around a definite, harsh and painful to listen to voice, in a situation where simple text would seem too mundane. Take these examples:
"DO YOU UNDERSTAND WHAT YOU'VE DONE?"
The androgynous voice grew harsh, as if scraping his mind. "Do you understand what you've done?"
If the character solely speaks in a tone that is harsh, would it be viable to use capitalization as emphasis or should you resort to describing it beforehand and using normal text?
