A non-believer can also possess these qualities to some degree, they still are image bearers. Although it seems like Calvinist like to see every non-believer as psycho-paths basically.
I think this guy from open door fellowship gives some additional insight
Fruit in the verse is singular, that is important.
While unbelievers may experience a degree of all of the attributes, Christians are experiencing them for one grand Spirit-driven
purpose; that the cross of Christ will be exalted, and the grace of God displayed as the transforming power it really is.
So let us exalt in the cross again today. While the Spirit is keeping a kind of moral order in a broken world, the Spirit’s truest work
and glorious fruit is His work of making new creatures in Christ. They alone will declare the praises of Him who is worthy.

When you were in elementary school.
When the teacher pointed to the map and told you that is where Russia is.
You accepted that how?
By faith.
