As well, we need to clearly distinguish "punishment" and "revenge". Revenge is an emotional response by those who have been wronged in the past. Punishment can mean many things (so perhaps we need more specific words), but I believe in this context it is meant to be a rational, conscious act to influence behaviour - though there are other kinds of punishment, and it can be difficult to distinguish. A parent may raise their voice very intentionally, without actually being angry, to gain attention, distinguish and underline a point, or elicit quick obedience (i.e. a "STOP!!!" when a child is about to dart on the road), but they may also raise their voice out of impulse, emotion, frustration, with no specific goal in mind and thus no clear direction or "win conditions". (I've only recently learned of the phrase "omnidirectional ass-chewing" [1], which is a very intentional demenour and environment for receiving marines to put them into a constantly stressful environment to train focus. It LOOKS like random angry yelling, but is in fact extremely studied, careful, and intentional. ) 1: Section 6, "Yelling" https://slate.com/human-interest/2013/03/why-is-boot-camp-so-intense.html https://slate.com/human-interest/2013/03/why-is-boot-camp-so...
