Can a bad breakup make you depressed?

It's true that depression does not have a single cause, it can be a combination of thing and events. In my experience, the loss of a loved one is the leading cause of depression.
When someone that used to be an integral part of one's life is no longer there, there is a high chance the affected person will fall into depression.

Do you agree?

I have come to understand that a really bad breakup can make one depressed. If you have someone that you have made a focal point of your life, breaking up with them can be disastrous.
This can eventually lead to depression for some people. This includes divorce in the marriage as well.
