bad people and bad things

Let these make us uneasy and helpless bad people and bad things always disappear, let the grass never wither;

让这些令我们不安与无奈的坏人坏事永远的烟消云散，让草儿不再枯萎；

Because with this little change, you will no longer be swayed up and down depending on whether good things or bad things happen to you, whether people (and their actions) are good or bad.

因为这个改变不大，你的情绪将不再因为好的不好的事发生在你身上而高高低低，无论他(和他们的行动)是好还是坏。

And he saves people, averts catastrophe, stops bad guys from doing bad things.

而且他救人于水火，逆转大灾变，制止坏人坏事。
