'unethically-executed' originates from the combination of 'unethical' and 'execute', where 'unethical' means 'not conforming to moral standards' and 'execute' means 'to carry out or perform'.

'unethical' changed from the Old English word 'unēþic' and 'execute' from the Latin word 'executus', eventually forming the modern English term 'unethically-executed'.

Initially, 'unethical' meant 'not moral', and 'execute' meant 'to carry out', but over time, the combination evolved to mean 'carried out in a morally unacceptable way'.
