> "didn't ever do anything wrong on purpose"

The fact that there are two ways to read this comes up in the criminal law context, where there's a question as to someone's mental state.

You read "on purpose" to attach to "act" – as in, "none of my wrong acts were acts I purposely engaged in." (Such statements can often be read this way in the law – it's about whether they intended the act, not the consequences.)

But I think most people stating that sentence intend to communicate that the wrong (or harm) was not deliberate, in that they had innocent motives, or a non-culpable mental state. And that claim shouldn't be all that hard to believe.
