The point is that what is "positive" and what is "negative" is up to the determination of each and every single different person. It is subjective and very misleading. It is not a theological term.
Faith, hope and charity are. And even hope, which is not an overoptism, is based on God's promises to us, not some silly feeling that everything will turn out all right even if we do stupid things in life. They won't. It also entails an adequate and objective assemssment of what constitutes reality.
Finally, those who are perceived as being "positive" have no more supernatural merit than those perceived as "negative" as these ingrained characteristic traits are of natural origin for the most part, NOT supernatural.
