You're conflating the facets of spirits with the religious interpretation of these beings, which shapes their perception by Andrastians as 'demons', the shunned First Children of the Maker who turned their back on their creator in jealousy over humanity. Anders' dialogue makes it clear that the Andrastian view holds demons as embodying different sins, which obviously isn't held by the Dalish, who follow the Creators.
Sloth Demon Codex Entry:
"The truth is that demons of sloth are named so because this is the portion of the human psyche that they feed upon. Doubt. Apathy. Entropy. They seek to spread these things. The sloth demon hides in its forms, a master of shapes and disguises, always in the last place you look... and from its hiding place it spreads its influence. A community afflicted by a demon of sloth could soon become a dilapidated pit where injustices are allowed to pass without comment, and none of the residents could be aware that such a change has even taken place. The sloth demon weakens, tires, tears at the edges of consciousness and would much rather render its victim helpless than engage in a true conflict. Such creatures are best faced only with a great deal of will, and only with an eye to piercing their many disguises."
Desire Demon Codex Entry:
Far more intelligent than the bestial hunger and rage demons, and more ambitious than the demons of sloth, these dark spirits are among the most skilled at tempting mages into possession. Many who serve the whims of a desire demon never realize it. They are manipulated by illusions and deceit if not outright mind control, although these demons are reluctant to resort to such crude measures. Instead, they seem to take great pleasure in corruption. The greater the deceit, the greater their victory.
Only demons of pride prove more fearsome opponents when roused. Their abilities to affect the mind allow them to assume disguises and even alter the environment to their purposes, not to mention the great strength and speed they possess if they should have to resort to more physical means. Most often a desire demon will attempt to bargain its way to freedom if overpowered—many stories exist that depict mages defeating desire demons to the point where a wish can be wrested from them. It should be noted that in such stories the demon almost always gets the upper hand even when the mage thinks his wish has been granted."
As evidenced by these codexs, the hierarchy of demons steams not from religious belief but from academic study; what we have here is the observation of empirical evidence that is then used to determine what part of the human psyche does a demon feed from; what "sin" they represent. In fact, the demons themselves will refer to each other as "demon", "sloth" or "pride". Likewise, Spirits will be the first to admit that they embody one virtue.
If the Dalish wish to dismiss the tale of the Maker turning his back on the spirits, that is perfectly fine. However, they can't dismiss myriads of research simply because it was perform by humans. And if they do so, then they are in the wrong and not the humans.
