Analyse: Aktiv dødshjælp – Glidebanen er en realitet
Erfaringerne fra lande, der har indført aktiv dødshjælp, viser drastisk stigning i anvendelse af aktiv dødshjælp over tid. Samtidig slækkes kriterierne for, hvornår man kan få aktiv dødshjælp og målgruppen for aktiv dødshjælp udvides. Argumentet om at aktiv dødshjælp er en glidebane er således ikke en hypotese men et faktum.
