Yes, they will mostly burn up in the upper atmosphere and are unlikely to kill people via direct impact. However, these large numbers of satellites will deplete the ozone layer and kill and blind people via increased rates of cancer and cataracts.

The chances of SpaceX/Elon Musk caring are ... I dunno ... close to zero. Even if government regulation demands that they do something about it, I expect they will simply defy the law.
