As for the fear that punishment instills in kids due to violence done to them or the threat of it, as long as the pain inflicted matches the pain the child him/herself inflicted on others as a result of his/her misdeeds, the punishment will only help, not harm, because that kind of punishment (though painful) effectively teaches the child about why he/she shouldn't do it again by forcing him/her to develop empathy for others.
Punishment is only malevolent when it's out of proportion to the violation committed, and/or when a child is punished for an act that he/she didn't do, or for an act that caused pain but was done for a reason (i. e. possibly in retaliation for another malicious act done to the child). But that rule applies to everyone, not just kids.
The only key difference between how to punish kids vs. adults is that the intensity of the punishment can be reduced for kids, since children are more psychologically malleable than adults.
Fear of punishment is BS, it does not make for well behaved children but for fearful children who will do their crimes in secret. It also does not teach them to be well behaved and behaving in accordance with the rules when they leave the house and you are no longer able to physically punish them.
