Take the money and run?
What's to stop the company taking your 250mill and just letting you die?
They had no real office/building, you couldn't contact them only them to you.
You had to 'kill yourself' and they dispose of body so just seemed a waste of time for them to actually go through the process and take that risk of you exposing them.
They had security and was willing to kill you anyway so i guess wasn't the first time someone had recalled there own memory and needed to be taken care of.
