The pros would include the life insurance death benefit that would be paid out to the beneficiary of the insured upon the man's death, subject to any exclusions or limitations in the life insurance policy.
The cons may include the cost of the life insurance, especially if the insured outlives the term of the life insurance policy and the coverage expires.
Also, the premiums may be so high and the amount of life insurance so low that after several years you may find the insured has paid more money into the life insurance policy in premiums than the death benefit that will be paid out. In this case, it may have been better to set up a savings account and just save the money that would have been paid for the life insurance, so there is money to pay for a funeral and burial for the man.
But, we don;t know how long any of us have to live, so buying life insurance is a way of providing some financial security for the ones we leave behind, whether it's to pay for final expenses, or provide money to our loved ones to use as they see fit.
