Bowe Bergdahl: deserter or hero?

(CNN) -- The sense of pride expressed by officials of the Obama administration at the release of Army Sgt. Bowe Bergdahl is not shared by many of those who served with him, veterans and soldiers who call him a deserter whose "selfish act" ended up costing the lives of better men.

"I was pissed off then, and I am even more so now with everything going on," said former Sgt. Matt Vierkant, a member of Bergdahl's platoon when he went missing on June 30, 2009. "Bowe Bergdahl deserted during a time of war, and his fellow Americans lost their lives searching for him."

Vierkant said Bergdahl needs to not only acknowledge his actions publicly but face a military trial for desertion under the Uniform Code of Military Justice.

A reporter asked Defense Secretary Chuck Hagel on Sunday whether Bergdahl had left his post without permission or deserted -- and, if so, whether he would be punished. Hagel didn't answer directly. "Our first priority is assuring his well-being and his health and getting him reunited with his family," he said. "Other circumstances that may develop and questions, those will be dealt with later."

Said Bergdahl's former squad leader, Greg Leatherman: "I'm pleased to see him returned safely. From experience, I hope that he receives adequate reintegration counseling. I believe that an investigation should take place as soon as health care professionals deem him fit to endure one."

At least six soldiers were killed in subsequent searches for Bergdahl, and many soldiers in his platoon said attacks seemed to increase against the United States in Paktika province in the days and weeks following his disappearance.

Many of Bergdahl's fellow troops -- from the seven or so who knew him best in his squad to the larger group that made up the 1st Battalion, 501st Infantry Regiment, 4th Brigade Combat Team, 25th Infantry Division -- told CNN that they signed nondisclosure agreements agreeing to never share any information about Bergdahl's disappearance and the efforts to recapture him. Some were willing to dismiss that document in hopes that the truth would come out about a soldier who they now fear is being hailed as a hero, while the men who lost their lives looking for him are ignored.

E-mails reported by the late Michael Hastings in Rolling Stone in 2012 reveal what Bergdahl's fellow infantrymen learned within days of his disappearance: He told people that he no longer supported the U.S. effort in Afghanistan.

"The future is too good to waste on lies," he wrote to his parents. "And life is way too short to care for the damnation of others, as well as to spend it helping fools with their ideas that are wrong. I have seen their ideas and I am ashamed to even be American. The horror of the self-righteous arrogance that they thrive in. It is all revolting."

Bergdahl wrote to them, "I am sorry for everything. The horror that is America is disgusting."
