"If I kill myself today, there shall be no more college tution, shoppings or even marriage to spend on. There won't be anyone to make me feel that I depend on them and they work harder because of me, or live a life full of issues. Just by ending my life, I would relieve them and me of so much, for I am nothing but a burden."
This is similar to what a girl may think of before she takes her life. This is a thought that may occur to her, on many occasions, until she actually does pick up that sharp tool, or that clinking bottle full of tablets.
There was a time when they buried the child alive if it was a girl. It seems cruel, to deny someone the right to live. But here's an another perspective. When you kill that child yourself, she doesn't remember it. She doesn't remember that pain. She does not feel the regret, the burden, of being a girl.
But when she kills herself, even if it takes an hour or so, she knows she is killing herself. She also knows the reason why she is doing it. She is buried in shame, in embarrassment and utter guilt.
All that misery did not exist when they buried the child. Even if it did, it belonged to them. And it's justice that way. She didn't ask for that life, she didn't choose to be "her". She isn't the burden that you make her feel like, out of her own damn wish!
