About をいいことに

()いことに is an expression in Japanese that may be translated as 'to take advantage of (A)', and generally refers to someone that is using (A) as a good opportunity to do something that is either immoral, or irresponsible. This construction is a combination of を, the い-Adjective ()い 'good', the noun こと 'thing', and the particle に. A more literal translation can be thought of as 'making good of (A), (B)', although the nuance is exactly the same as 'to take advantage of (A)' in English.
()いことに will be seen following verbs, nouns, い-Adjectives and な-Adjectives, but will be preceded by either の or なの in all cases, based on standard conjugation rules for の.
