Wait, Why Control Population?

You say we are many
And population should be controlled

If my mother planned for two
I could not be born
That is murder!

If I only plan for two
That is selfishness
And murder!

And if I happen to be sterile
I will still feed other people's children
It does not matter

Who knows who will be who
When a woman is full?
But still he yearns to live

The first two may be bloody demons
And the last eight human angel
Or vice versa. It must be

The good will compensate the bad
For it is in nature
To destroy itself
And rebuild.

If you think we are many
Please leave Earth
For Us.

This is for my lecturer Mr. Okungu who thinks it is not right to control population. As usual, my credentials escape me. I do not know what.
