Sigh let me explain once again. How would Dharma know about Jacob? So it is a fact Dharma knows who Jacob is. They Also though god loved and/or loves Jacob so that means they problaly used to like or never stopped liking Jacob. Also if you remember what videos where edited they were edited by Dharma not the Others. Like Caleb edited that one video. Some Dharma workers took out so clips. Putting clips in the middle of a video would be impossible. So the others did not add that in. And the others did not make that video because it is obviously Dharma plus is labled "DHARMA Brain washing video"

You need to understand that all those things you listed are not that hard and are necessary for them. Editing a old video made by Dharma in the 70's to add clips in the middle of it and still make it work is risky and difficult. They would just use the ordinary video. He didn't want to turn Karl to Dharma's side he just wanted to put him in a place where he can't escape until Ben decides what to do with him so he won't get Alex pregnant. Also sense Ben raised Alex he does care for her. If you remember when you were a kid you should remember what they would have done if a boy got your pregnant. All parents/guardians overreact on things like this.

Jacob had to at one time be somehow involved with Dharma. For the very least Dharma KNEW who Jacob was. I am not sure if he worked with them or not.
