 Guevara later remarked that through his travels in Latin America , he came in " close contact with poverty , hunger and disease " along with the " inability to treat a child because of lack of money " and " stupefaction provoked by the continual hunger and punishment " that leads a father to " accept the loss of a son as an unimportant accident " . It was these experiences which Guevara cites as convincing him that in order to " help these people " , he needed to leave the realm of medicine , and consider the political arena of armed struggle .
