Do you know how hitler was better than voldemort ? Nobody made it out of his chamber alive.
Are you suggesting that Hitler should have been more successful at pursuing his goals?
He should have done better.
It is wrong to make jokes about the Holocaust, because many people's grandparents have died in those gas chambers, and it would be very hurtful for them to hear you making light. Furthermore, this kind of joke makes it sound like you wished that the Holocaust had taken even more lives.
They shouldn't be so sensitive, I was only joking.
But jokes about real people dying in the gas chamber are not funny. They are painful for those that family who went through that.
