Of course it should matter if it's a good idea. The roll of the Justices is to interpret the Constitution and the first thing to consider is what was/is the purpose of the Constitution. If one is to interpret something it's extremely beneficial to understand the reason and/or context in which it was written. For example, one writes, "Wait till I get my hands on you!" If that was written by an adversary it would be reasonable to interpret it as a threat. However, if written by a lover it takes on a whole new meaning.
Now, let's look at the Preamble remembering that (Excerpt) The Preamble to the United States Constitution is a brief introductory statement of the Constitution's fundamental purposes and guiding principles. It states in general terms, and courts have referred to it as reliable evidence of, the Founding Fathers' intentions regarding the Constitution's meaning and what they hoped the Constitution would achieve. (End) Now that we know the reason/context in which it was written we read (Excerpt) We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America. (End)
