Because they, after learning that they were responsible for the extermination of their creators (the precursors), realized they were unworthy of carrying on the mantle so the decided to make humans the inheritors o the mantle and commit mass suicide as a punishment for violating the mantle they held so dear...
Plus, the flood was their punishment for destroying the precursors, so they probably realized the rest of the life in the galaxy did not have to pay for their sins...
Wait, if the Forerunners made humans the inheritors because they considered themselves unworthy, why did they create Shield Worlds? To save themselves? I mean. You pointed out that they wanted to take themselves with the Flood as punishment.
The shield worlds were created before the flood had the help of mendicant bias, which took forerunners by surprise, so they could not flee, or evacuate to the shield worlds... They, for a moment, thought they would have time to escape...
That was before they thought they were unworthy of the mantle.
