He suffered the horrors of war, "...It was not bad fun in a way."
He found the experience of being hit by a near-fatal bullet, 'fairly interesting'.
He almost got thrown in jail where one, 'generally stays forever, with or without a trial'.
And yet--as a result, he is left with, "...not less but more belief in the decency of human beings."...Go figure.
My thoughts are that during his experience of war and bonding with his band of brothers, he developed a same sex attraction and went insane.
My hypothesis of his becoming a homosexual, explains his attraction to pain and his faith in the decency of his enemy.....Nevermind.
I've read no evidence anywhere that Orwell went homo. Believe me if he did, the gay rights groups today would be touting that fact.
