Commitment to Halacha

Hello,

You wrote this in one of your articles:
“Before even beginning the discussion, I find it my duty to preface this by saying that, contrary to the understanding of Halacha implicit in your question, the decision in every area of ​​life, including Halacha, is yours and no one else’s. Even where Halacha unequivocally says so, you are the one who must decide whether to comply with this obligation or not. This is not a privilege, or any kind of privilege, but an obligation that the Torah imposes on us, in its words, “And you chose life.”

I didn’t understand exactly when we should comply with the Torah’s requirements and when not. Why did you choose life?
