Damien knew he was being harsh, but it was necessary.
Someone like Ran couldn't learn through easy means.
She was entitled beyond belief. Her world revolved around her, and it was clear she never had to face the consequences of her actions.
If someone grew like that, they were bound to become a terrible person simply due to their ignorance. That was not bliss, but a ticking time bomb just waiting to explode.
And it exploded.
It exploded right in Ran's face and took the person she cared about most.
How was someone who never learned to cope with negativity to respond to a stimulus like that?
Ending everything was an easy choice. She was someone who would always pick the easy choice because she simply couldn't see the other choices at all.
Damien hated people like her. He hated people who lived in this cruel and cold world and somehow maintained the thought that they were above its rule.
