You don’t “improve” anything by codifying the killing of innocent persons, by ignoring the most important stated founding purposes and principles of this free republic, by abrogating the explicit, imperative requirements of the constitution, or by continuing to feed the delusion that courts have any proper jurisdiction or authority to make laws, veto laws, or to amend our constitutions.
You are making the mistake of thinking that the killing of children is currently illegal.
It isn’t. The courts have approved it.
The only steps forward have been through appealing to the conscience. These steps have brought us to a somewhat better place. Any other gradual improvement, such as the no-pain bill will also appeal to the conscience.
The last election, when we chose to run John McCain, an inept candidate, injured the position of life far more than has anything else in the last 2 decades. It enabled Sotomayor and Kagan to be appointed to the Scotus. With a conservative president, that would never have happened. Stevens might still have retired...or died. Souter probably wouldn’t have retired.
