You can't be completely sure of ANY quality before living together.
But even if you could, I don't think that's the right question to ask. A spouse is a package deal. It all depends on the combination of qualities and how they balance each other out, because ultimately, over time, people change and some qualities become more cemented while others kind of wane.
And there is no one good quality that makes up for a million bad qualities. Period. Even kindness does not make up for a spouse being lazy, stupid, and irresponsible, because at the end of the day, you are going to have your live intertwined in this other person's life.
What you are looking for in a spouse is a constellation of qualities. They may individually wax and wane over time or as the person goes through different stages of life, but they form a pretty solid web or network.
Kindness is one, but also hardworking, responsible, strong sense of humor.
