[PL 431] Moral degenerates

After a year of social protest in Israel, an Israeli citizen set himself on fire in Tel-Aviv on Saturday. In doing so, Moshe Silman has followed in the footsteps of many who had engaged in self-immolation as a form of social and political protest.

Being ignorant of the meaning of this act of protest, apparently, Prof. Amir Hetsroni said the following:

Pyromaniacs do not impress me. Unlike people like me, people like Silman do not contribute to the Israeli economy. Although starting fires is entertaining, we have to take into consideration the costs of putting fires out, and then realize that we lost more than we gained.

Now, from the perspective of virtue ethics, can we infer something about the moral character of a person from what s/he says, just as we can infer something about the moral character of a person from what s/he (habitually) does? If so, what can we infer about the moral character of Prof. Amir Hetsroni?
