The attitude that characterizes the ethical problem of conflicts of interest is "help yourself and help those closest to you".

One example of a conflict of interest is this situation:

The organization you’re working for (Department of Tourism) wants to advertise an advocacy and the organization has shortlisted some prospective television stations. One of the television stations shortlisted is owned by your brother and it was the one selected to advertise the advocacy. Although the proper bidding and contract agreement was observed in selecting the television station, this situation shows a conflict of interest because you’re directly related to the owner.

they all focused on themes about the inevitability of death.

you should think about the answers you give and expect the same form your questions.
