Do scammers even believe their own lies?

Someone online with an obvious staged picture that refuses a video call has been trying too hard with his idiotic love messages.

I've already clearly stated that as soon as he starts asking for money, any card (gift card, debit, credit, etc) or personal information such as my address or whatever, I'm going to block him. I've also requested for the 2nd time for him to show up on a video call or else he's a liar.

He still had the never to feeling offended that I distrust him so much, that he's hurt, etc. Since he's trying too hard and being so persistent I think now I'm going to waste his time and pretend to go along with it. I want to scambait him. Seriously do they even believe their own lies?

I'll start by issuing him a fake apology for ''distrusting him'' and play dumb. I'll give him fake information if he ask, just like they lie so much, I'm going to lie too.
