If we define "intent" as the intent to establish certain rights which protect individuals while giving them the freedom to protect themselves, then yes, we should follow that intent. The other intent was that the Constitution could be amended and this is just as important as any of the rights, key examples being Amendment 13 which outlawed slavery, Amendment 15 would not deny the right to vote based on race and the 19th amendment gave the right to vote to women.
The initial 10 "Bill of Rights" established basic rights for individuals and in particular, the first Amendment has come to be the key liberty which allows citizens to question their government without fear of retribution of any kind. It's hard to say that one freedom is more important than another, but this freedom guarantees freedom of religion, speech, press, and right to assemble (protest). It is a significant freedom and one which allows citizens to keep their government honest and/or from abusing its power.
The ability to amend to constitution is also incredibly important. In the preamble to the Bill of Rights, the first declaration is:
THE Conventions of a number of the States, having at the time of their adopting the Constitution, expressed a desire, in order to prevent misconstruction or abuse of its powers, that further declaratory and restrictive clauses should be added: And as extending the ground of public confidence in the Government, will best ensure the beneficent ends of its institution.
