Who decides who must suffer and when they definitely will?  There are many parents who, though at first did not want children, found incredible joy in that new life, while other parents who wanted children and had them abused them.  So then, is the government to condone the destroying of life based on suffering?  No!  Each one has the right to determine whether they want life or not: that's called freedom.  Even then, the suicidal are often locked up into institutions to be convinced not to destroy themselves.  Society, even from a purely evolutionary perspective, needs to uphold the value of life, for if it doesn't, anarchy ensues.  It is no more moral to kill a child based on convenience, even if that child was created mostly by a woman who deems it inconvenient.  For us to presume that its existence would merely be suffering therefore is foolish.  We don't know, and a society held up to a standard of responsibility--the sanctity of life--would very well change its promiscuous ways with that responsibility in mind.  If it didn't change, then what's the point of sexual education to begin with!  Why should we inform someone of any form of sexual responsibility if there is no one will change their mind anyway?  Destroying the child is by no means a solution to this either, only a degradation into ungratefulness and worthlessness.  Life is a gift to be cherished.
