It's a very religious idea that "the justice system ought to be about meting justice", particularly a Protestant / Christian idea. The very phrase "meting out justice" is a biblical one.

Secular societies are more interested in the outcomes than the moral righteousness of the system.

That's an extremely narrow view of "secular".

Not all secular societies or people are consequentalists. Some are at least as interested in the moral righteousness of a system -- in its means, in its processes, in what it does on the way to its ends -- as they are in what that system accomplishes. There are secular humanist deontologists and virtue ethicists.
