Below are excerpts from the interview:

On accepting money from Natalee Holloway's family in exchange for the location of her remains
VAN DER SLOOT: I have had five years long that people have just been blaming me for something. And yeah, I have a lot of anger built up because of that also. And yeah, at one point I just thought that, OK, you know, "You keep insisting that you want to give me this money. I've already told a lot of different stories. I'll do it--I'll do it again." And yeah, I know it's very wrong--very wrong, what I did.

Why he told so many different stories about the disappearance of Natalee Holloway:
VAN DER SLOOT: There were--people were paying me to--paying me to--yeah, to make up stories, and I was really good at making up stories. Everybody keeps coming at you, asking you questions, asking you stuff and, you know, you don't know something, and finally you start to think, `OK, well...(censored by network)...you. If you--if you want something, then I'll tell you whatever you want to hear. Sure. I misused the situation for my own advantage and I feel bad about that. And if I could change that, I would take it back for sure.

On the impact his actions have had on his family
JORAN VAN DER SLOOT: For everything that happened since 2005, all the things said in the media and everything, I feel guilty for it, yeah.

VAN DER SLOOT: I was doing a lot of things that I shouldn't have been—I shouldn't have been doing, and mostly only going out all the night and sleeping all the day. I have always been very, how you call it, impulsive, always been--take action right away and make a decision immediately and not think about what the consequences are.
