Humans are really scary aren't they?
There are all types of people, with differing characters, agendas, attitude, and so on.
We never know what the other person is thinking, in doing this action, or saying a particular sentence. We don't know the person's hidden agendas, character, reactions. We seek to understand others, yet we do not know ourselves. We start to doubt people. We start to question their motives. "This world isn't as pure as I thought".

And we all have this tiny seed of darkness that lies in our heart. Waiting for a chance to bloom beautifully under the many kinds of stimuli we can provide from our daily lives. From anger, sadness, fear, and other negative emotions. It slowly grows, from a small seed, branching out, eventually growing into a bud, blooming into a flower, then it bears fruit. The small seed, after months, years of growth, finally bears fruit.

A fruit we are unconscious of, that we do not know how to handle.

One day things go awry, and the person breaks.
The fruit has dropped. The person unleashes everything from within. That darkness engulfs everything in its path, enveloping others in fear.

That person can no longer be called a human, is it not?
Just a beast, a mass of hatred, a monster. One cannot even be said to be living anymore.

But eventually that darkness engulfs oneself. Despair drives home, and we start to self-destruct.

All alone.
