Consideratmpassion Compassion

I translated this term: 思いやり and it appears that a better translation would be "compassion" or "kindness." These terms are more friendly than "consideration," which to me is colder and more analytical. I don't speak Japanese, so my sincere apologies if this is incorrect/inaccurate!

You must not be treated without consideratshould treat other people with compassion. You should treat other people with compassion.

If this is general advice, it makes more sense to instruct your reader on how they should act, rather than how they should be treated, since they don't control how they are treated but can change how they act.

You must notshould not be treated without consideration. / No one should be treated without consideration. You should not be treated without consideration. / No one should be treated without consideration.

The other correction is excellent, but you can say this too. ここで、Must を使ったら、ちょっと命令みたいで、shouldは「するべき」な感じがある。

ConverselyLikewise, you should show gratitude and respect from the bottom of your heart when someone has consideratshown compassion for your family or you. Likewise, you should show gratitude and respect from the bottom of your heart when someone has shown compassion for your family or you.

"Likewise" sounds a bit more natural than "conversely" because we're continuing to talk about a related topic. "Conversely" would work better if we were beginning a sentence about the converse (opposite) situation.
