Punish if same. With all my respect, I think that the person who puts it refers to something in the past! And according to my point of view, it should be. Is auto flagelaba! And if you think about it, when we made a mistake, or mistake, erroneously abuse of power above our children. Perhaps guilt not are you? Leaving the home who we ofendimos and humbly apologize, also is to impose a punishment. And they do not necessarily have to be physical whippings. Those who fall into the feelings when we ofendimos. Those hurt more. To criticize. Disqualify. Condemn. We are also committing a scourge.
In reality and, given that it is clear that the prefix is idle because no one autoflagela to another person, the verb in the infinitive should be " flagellar " and never " self-flagellation " as sometimes we hear say. It would be as a flogging ( punishment spanking ) exerted against one's self, in real and physical sense ( unlikely ) or in the metaphorical sense of reproach and sour self-censorship.
