No. Free will doesn't mean we ought to support or oppose any particular action, only that we can choose it.
right -- so the classic, "I personally oppose you euthanizing yourself, but you have the choice and I won't attempt to put the state apparatus in your way here." that's all I'm looking for
That doesn't really match up with your title/OP. Are you trying to make a Christian argument for the state to ignore euthanasia or are you making a theological argument about euthanasia itself?
a theological argument that "frees up" the Christian towards new attitudes about the (ultimately technologically-driven) changes in the end of life process.
The idea that the Christian
should be 'freed up' presupposes an ethical argument that you haven't actually made.
