But I fear there will be many, when presented with a choice, will feel it is their duty, rather than their will, to opt to do what others consider is the right thing to do.
Hopefully such fears will be addressed in more detail as the bill goes through its committee/report stage and it is possible that this particular bill will be addressed by a committee of the whole House. Either way, MPs will be able to propose amendments on a day to day basis as the committee discusses the bill.
However you might like to consider the possible pressures on someone who is dying right now. I can think of three pertinent ones straight away.
1) The pressure of not wanting any member of their loved ones to see them in a debilitated condition
2) The pressure of continuing to take life prolonging drugs because of the wishes of their loved ones when they would far rather not prolong their agony.
3) The pressure of attempting to commit suicide(whilst they are still able), often in a lonely and painful manner and running the risk that they will only end up surviving the attempt.
However if your bottom line is one of faith, insisting upon the absolute sanctity of life, then I feel that there is nothing I could do to persuade you otherwise. Suffice it to say that I am pleased with the result of the bill's passage through Parliament so far.
