Yes. There is nothing about a sacrament that somehow magically keeps a person from going off and doing bad acts if they so choose.Catholic sacraments are not meaningless rituals but they do depend on the state of your interior disposition.
And Hitler would not be the first or only person to have ties to a Christian church and then go off and do horrible acts. Plenty of Protestant Nazis also who participated in his genocides and oppression.
