Insulting me won't make the purpose of assassinations to be about fear.

But sure, let's go with the second sentence. There were only two sentences in the definition:

Terrorism is intended to coerce or intimidate governments or societies in the pursuit of goals that are generally political, religious, or ideological.

That is also not what assassinations are usually about. They are usually not about coercion or intimidation. They are about retribution or seizing power.

Feel free to insult me on that front too.
