So just to clarify,
We cannot impose our own views on others because we all have the God given freedom to think for ourselves and form our own opinions.
Let's ignore the notion of god in this as we do not know whether god even exists.
So let's break this down. Image there are two options X and Y (in this case X is choosing assisted dying towards the end of life and Y is choosing not to use assisted dying but different end of life options). Some people would prefer to choose X, others would prefer to choose Y. But that will only be a fully free choice if there is no coercion from societies of individuals nor sanction on the basis of choosing one option or the other. If society or individuals coerce or apply sanction then they are imposing their views on the individual choosing between X and Y. And those pressures might be subtle societal pressures that X is preferable to Y (or vice versa) but, of course the most draconian of pressures (and the greatest imposition of views on the person making the choice) is to declare that one of X or Y is unlawful and that if an individual chooses that option they may be prosecuted and jailed.
So any situation where one of X or Y is unlawful is a situation where societies are influencing the choices of individuals as those choices are no longer free choices, but subject to sanction and therefore the societal views are imposed on individuals. And, of course, if an individual supports X being unlawful as in their view X is wrong is also imposing their view (through retaining a draconian section on people choosing X).
What I was hoping to do was that by explaining my reasoning from a Christian perspective I might influence the reasoning of other people to reach what I consider to be the objective truth as seen in God's eyes - namely the sins of despair and murder.
But that is clearly attempting to impose ones view on another. If you weren't attempting to impose your view AB, you would simple step back and allow the individual to choose freely without applying pressure to adhere to your view.
So if this is a situation where X and Y are considered equally valid under the law you might still attempt to impose your view on an individual to influence (or pressurise them) to follow the option that aligns with your view. But that isn't the case here as X is currently illegal and you want it to remain illegal. So not only do you want the greatest level of societal imposition of views - X being illegal, but also wish to attempt to impose your views directly in a manner attempting to influence an individual to choose Y.
If I were an MP I would certainly vote to keep assisted suicide unlawful as a means to help prevent people committing such sinful acts for the sake of their own souls.
Of course you would AB, and I image were assisted dying to become legal and there was a opportunity to make it illegal again you'd vote to ban it. Which is, of course, the very clearest evidence that you want to, and would act to, impose your view (that X is wrong) on others by preventing them from freely choosing X without risk of severe sanction.
