Why did moshe leave sighet and how did the rest of the community react to what had to say when he retyrned?

Moshe left Sighet after being deported with other foreign Jews to a concentration camp, where he witnessed horrific atrocities. When he returned to Sighet to warn the community about the impending danger, many residents dismissed his warnings as the ravings of a madman, unable to believe that such horrors could happen to them. His desperate pleas were met with skepticism and indifference, as the community clung to the hope that they would be safe. This disbelief ultimately left them unprepared for the tragedy that would soon unfold.
