As a Christian, I would never hold anyone who isn’t a Christian to a biblical standard of ethics because it’s literally impossible to keep on your own. That’s the whole point of Christ’s sacrifice, that because we can’t keep to the Abrahamic laws, God is justice, and as such demands that a punishment must be met out, so Jesus is offered as a sacrifice for us so that we might be blameless before his sight.

God gives us free will, and we’re allowed to do whatever we want with it, but the biblical standard is there because staying inside that box will lead to the most abundant life you can have on earth. If someone does accept Jesus as their savior, they get the Holy Spirit within them that as they draw closer to God, will influence their hearts and minds to be more Christlike and as such cause them to live more inside that playground.

My heart breaks when Christians try and use force to cause people to follow biblical standards. They’re missing the whole point of the Gospel. Works have nothing to so with it, it’s all based on faith. The only thing that matters is having that relationship with Jesus Christ. Then hopefully as you see that relationship grow the person sees that the law is there for our protection, and living inside it is the best way to achieve fulfillment here on earth
