Do you think Hitler was an evil person or someone who genuinely believed what he said and thought it was right

hitler lived through ww1 which was far more horrific than the second, most of the deaths were from trench foot, sickness and infection, soldiers would start to rot before they had even died and officers would shoot those who fell asleep during their 7 hour guard duty (which was a death sentence to begin with) as well as perceived "cowards" before they could infect the rest of the trench with contagious fear due to having no knowledge of the effects of combat fatigue during those days, even the bravest hardest soldiers start to break down after 60 days of continuous combat, to the point of a falling into a vegetative state. and then theres the rats, dog sized rats gorging themselves on the dead and dying..

there is a story that hitler was with some of his comrades in a trench when he left to take a piss, when he came back he found that a shell had wiped them out and caved in that section of the trench, he survived due to dumb luck, these experiences destroy minds forever. i believe monsters are not born, they are made.
