You started: "I punched a few of the gangsters and I say to them ...". The tenses here are inconsistent. I went with the first tense, "punched". You can also say "I punch a few of the gangsters and I say to them ..." However, we don't usually talk like this in the simple present tense. It could also be historical present of course. The second part, "I told you I would b
No I meant so I already punched them in the face and now I say to them, "I had told you I will beat you up If you voilate any code of conduct." This could be referred to present tense because I m still sticking to what I said so the action is still there.If I did in contrary to what I had said then i would definitely refer it in past tense. So I m correct?
"I had told you" is an unnecessary overcomplication here. Just say "I told you".
"I told you I will beat you up if you violate any code of conduct" is possible if the beating up is still threatened but has not yet happened. In your scenario, I thought the beating up had already happened. If it has, use "would".
