Mike's reasons for going back to Vietnam to get Nick goes beyond them just being friends; the primary reason was that he promised Nick he would bring him home. Mike could not face himself with the guilt of going back on his promise. When he goes home without Nick he can barely face Linda, Nick's fiancÃ©, knowing that Nick is somewhere back in Vietnam. Mike decided to go back to Vietnam to find and bring back Nick, but when Mike found him, he didn't recognize Mike and he was about to sit down at the Russian Roulette table. Mike sat down in the seat across from him, trying to stop him but when he realized it was useless to reason with him, he played Russian Roulette with him. Mike got out alive, but Nick died due to the bullet through his head. In the end Mike kept his promise, bringing Nick back to his friends and family, whether he was alive or dead.
