ever在本句中是never的意思，跟否定词连用（前面有否定wasn't，承前省略了not），即：not ever = never，意为：“从来都不；在任何时候都不”。

例如：

I would not ever hurt them. 我决不会伤害他们。

Do not ever say that again . My uncle is very conscious. 千万别再那么说，我叔叔非常敏感。

This kind of decision cannot ever be made in a vacuum. 这种决定绝不能脱离实际。

In my career I haven't ever made someone do that and I never will.  在我的事业中，我从来没有要求谁那样做，我将来绝也不会。
