In a perfect world, where everyone acts responsibly, so many evils could be avoided. but the world, unfortunately, is not like that.
It is true that children do not deserve to be treated as a burden and I wish we could avoid all the pain.
For my part I try to act responsibly and do my bit, but I also try not to judge others because I am not perfect.
We only have to give the best of us to make the world a better place.
