This depends on different variables and circumstances. If it is affordable to you, then yes, it is possible you should have life insurance for a number of different reasons.
The first and most important reason is for your dependents, such as children, spouses or even elderly parents who are relying on you to provide the financial security and need you to care for them. Should you die, you will no longer be able to provide for your dependents, which is why it is important to have life insurance to provide for these dependents.
It is also important to consider how your death will affect your surviving relatives and dependents. Funeral expenses can be covered by life insurance as can be debts and bills that you will leave behind, a burden on your survivors if you do not have the financial abilities to pay these off, which is another reason why life insurance is important.
However, if you do not have any dependents, you might not need life insurance. If you are financially secure and have adequate sources to provide for you and your debts, bills, etc., then it is quite likely that you do not need life insurance. Many people, however, that do not ”need” life insurance purchase it regardless as a way to leave money behind to one or more beneficiaries. It minimizes the tax consequences of leaving behind money to those beneficiaries.
