If I understand Popa, he is not saying that Hashem doesn’t care if we sin or not, but that Hashem loves us and has forbearance with us and wants us to do what is good for us no matter what, even if we make the wrong choices sometimes. This is implied in the 13 Middos HaRachamim.
In the kabbalistic sefer Tomer Devorah it describes Hashem’s complete Kindness and eternal forgiveness and tolerance, and how to emulate Hashem in these ways. The parts of this sefer that are somewhat understandable are very beautiful and it is well worth reading.
If we should act this way to all people, even more so we should treat other Jews, and those closest to us, our families, with loving guidance and tolerance and kindness regardless of their choices.
For example, suppose someone ch”v has an anorexic child. It is an aveira for that child to not eat. Does Hashem not love this child because they are doing an aveira? As the parent, do you hate the child and treat them as a sinner, or do you love them and try to help them?
You may need to force feed the child to get them back to normal and threaten them with the hospital, but we know that this is not a healthy or good solution. The child needs to eat out of love, for their own good, and the fear is a temporary measure at best.
A healthy body wants to eat, and itself is scared of not eating. And a healthy soul wants to do good things, and itself avoids and stays away from evil and temptations.
Similarly Hashem wants us to educate our children to be like ????? ?????? ?? ??? ??? ?? ??? ???? ???, and once you are serving out of love and not for the reward, because you are healthy and want to do good and have a loving relationship with Hashem, then of course, ???? ???? ???? ?????, you will avoid evil.
