What is 'love'? A lot of people don't get what it means to love yet they believe they are in love.
What is 'hate'? A lot if people don't get what it means to hate yet the believe they hate others.
So then, tell me than what is a 'monster'. Kids believed that monsters are what lies under their bed or in their closet. Teenagers believed that it's their parents. Adults believed that it's their boss.
What they don't get is that 'love', 'hate', 'monster' or any other word alike don't nessesary means what you think it is.
After all the higher-ups believe that a 15 year old boy that can shift into something they're afraid of is a 'monster'. They believe that they are 'superior' compare to 'commoners'. They believe they can do whatever they want just cause they're 'better'. They believe that they're 'God'.
They play with 'commoners' life just for the fun of it. But really who are the 'monster' here? The titans? The 15 year old boy who watched his own mother die? No, to be honest no one is really the 'monster' except in this case the higher-ups are the 'monster'.
Yet once the 'commoners' fight back and kill, they become the 'monster'.
So really in this world there's no such things as 'feelings' or 'monsters'. It's just how you think.
What about 'love' than? The couple down the street may look like they're in 'love' but behind closed doors it seems more like they 'hate' each other.
But who am I to say after all I'm just a 'human' like you.
