No a DGR is by definition the most stable place to put something, as it has been specifically sought out and designated by a geologist for this purpose.

My problem is with the human parts of this that are all convinced this is an easy option, corners will be cut and the consequences will outlive all of us by orders of magnitude.

No, the idea that producing radioactive waste is ok because we can always find places to ferret it underground is one of the stupidest misunderstandings of how humans bullshit, cut corners and ignore inconvenient environmental contexts I can imagine.

We have not been studying the earth that long compared to other sciences, even Plate Tectonics is largely still not understood in many of the important aspects, I am sorry but when you turn around and say "nothing will happen to this rock for 100,000 years" you may be right but also there are going to be lots of things you don't forsee and more importantly humans are going to cut corners you would never have imagined they would cut.

I am not saying we need to get rid of all nuclear power, I am saying it is nowhere as foolproof as an energy source as nuclear power advocates constantly push, it is not the future alternative energy is.
