In World War Two, many thousands of disabled people were murdered by Nazis. The Nazis did this because they believed in non-voluntary euthanasia and forced eugenics, which is a philosophy that advocates reproduction by humans with 'desirable' traits and discourages reproduction by humans with 'undesirable' traits. They thought that disability is bad and disabled people are a burden on society. Many people still believe those things. In 2013 a councillor in Cornwall called Colin Brewer said that disabled children 'should be put down' to save money. He was found guilty of misconduct but the council could not fire him.
