Port Adelaide, Carr's desired destination next year, refused to trade for the 2004 premiership player during the AFL's exchange period, leaving the purple haze with no choice but to delist the once vice-captain.
Carr, who sought a trade from the Power to his native WA at the end of 2004, cost Fremantle picks 11, 27 and 45 just four years ago.
But the 28-year-old made no apologies for his decision to return to live in Adelaide with his SA-born fiancé, Karolina.
"Fremantle was great to me over the last four years and I was happy when I went back there with the way they looked after me," Carr said on Wednesday.
"They gave me a great opportunity to play with my brother and in front of my family, but now it's a different stage of my life.
"I thought I gave Fremantle four good years and it is probably a hard thing for them [me leaving] considering I was there four years and they gave up a fair bit for me.
"But this is a life decision. I wanted to live back here [Adelaide] and, at this stage of my life I thought it was time to come back. AFL is a funny sport with the draft –everyone gets drafted away – and people get traded, that's just the way it is these days."
Fremantle has a pick (No. 3) ahead of the Power in the December 16 NAB AFL pre-season draft, for which Carr will nominate, but is unlikely to take a risk on re-drafting the veteran, who has stated his intention to remain in Adelaide.
Carr played in finals just once (2006) while at Fremantle, but despite the team's disappointing '08 season he was confident coach Mark Harvey would bring the club success in the future.
"Like I said, AFL is a funny sport and there is only one team that can win it [the flag] every year," Carr said.
"Freo has had it hard, especially in the early days, but I think they're on the right track now. I think Harvs [Harvey] has got the young guys going well and I think there are some positive things coming their way in the next few years."
