Because you can't just decide to take someone's freedom of choice away. Consent and personal agency are important and if the only way you can keep people agreeing is to deny them any other option, that's slavery. Personal freedom does need to be balanced with existing in a society and respecting the rights of others, sure.
But this country declared one people superior and certain other people 'the enemy' and committed genocide for that belief. Seventeen million men, woman and children were murdered just because they were considered not worth the resources it took to keep them alive. Others were forcibly sterilised because these people decided they should never be allowed to breed.
Eventually, a generation or two down the road, if they'd got away with it? Maybe those generations would see it as normal and fine. Or maybe, they'd look across the borders and see people who didn't have their lives mapped out by the state and decide they'd like the try that. Which makes them an undesirable and gotta go.
