Do you think its true that once a dictator always a dictator?

At a town hall yesterday Sean Hannity asked Trump about the media saying he would be a dictator if he returned to the Oval Office. Trump initially shied away from responding, but when asked a second time he said he would only be a dictator on the first day of his second term.

I think that is the biggest lie Trump ever told because he is likely planning on being a dictator for ever if he gets back in the WH. Cheers!
