I have my dead fathers discs that say destroy do not open even if deceased.
This is intriguing. Will you open your father's disks?
It feels like he's trying to control me after his death, so it's time to give him a lesson by opening them
It is understandable not wanting you father controlling your life even in his death but you should honor and respect his dying wish. You should not open the disks because you father wanted them destroyed and not opened.
I have to look into it, but I want to know what's on them.
The curiosity is very understandable, but you should honor his wishes about the discs. There could be information on there that could ruin lives if it gets out. I vote for destroying them.
