Yes and no. His work on the humanitarian front after leaving office is without question more impressive than what any other modern day president has done, including Clinton and his "foundation"...
Politically, though, I won't call him honorable.
Carter issued the executive order that continues to deny the 52 Iranian hostages who were held for 444 days the ability to sue Iran for compensation. Instead of being treated as prisoners of war, they were simply given back pay plus a per diem rate, which essentially worked out to $22,200 each.

Over 30 years later, it's still not undone, which is also a reflection on *every* sitting president since then. Congress has finally started to act -- instead of seeking compensation from Iran, they're going to tap into the sanctions collected from companies who have violated the embargo, which will work out to a payment of several million per hostage. Bills have passed in both chambers of Congress, so let's see if Obama signs it...
After leaving office, Carter has twice spoken out against the policies of sitting presidents (W and O), something that no other former president had done in modern times. Having an elder statesmen undermine a current administration isn't what I'd all honorable.
