'immorally-executed' originates from the combination of 'immoral' and 'executed', where 'immoral' comes from Latin 'immoralis', meaning 'not conforming to moral standards', and 'executed' from Latin 'executus', meaning 'carried out'.

'immoralis' transformed into the Old French 'immoral', and 'executus' into the Old French 'executer', eventually forming the modern English term 'immorally-executed'.

Initially, 'immoral' meant 'not conforming to moral standards', and 'executed' meant 'carried out'. Together, they evolved to describe actions performed unethically.
