Reading the study (https://sci-hub.se/https://doi.org/10.1080/09515089.2019.158...) the questions don't sound overly morally charged. They're certainly what I'd imagine a normal person may find moral questions, but are otherwise fairly middling in terms of moral impact. Other than vegetarianism, I'd say many of the don't have moral weight, at least not how they were asked. And even if you had considered them moral, it would only be from a deontological, or possibly virtue, ethics perspective.

The behaviour is a little more damning, but they only show evidence from two different scenarios. One of those scenarios had to do with charity and once again I feel like donating to charity is not overly morally charged. And if it is, it's certainly not the way they presented it.
