[What? Some Random Thoughts] Unrelenting is an extreme; permissive is another

Unrelenting:
      ADJ 不顾一切的;不留情面的
      If you describe someone's behaviour as unrelenting, you mean that they are continuing to do something in a very determined way, often without caring whether they hurt or embarrass other people.

Permissive:
      adj 1: not preventive [ant: {preventative}, {preventive}]
      2: granting or inclined or able to grant permission; not strict
         in discipline;


Some thoughts about these two words.
If unrelenting is not a good practice, neither is permissive. One is ruthless, the other is lack of discipline.
How to strike a balance? Wow, that is the wisdom and such a long way to go.
