A) you should immediately discount the expertise of people just learning this now
B) a designed pathogen will kill a person this century, full stop, no way to prevent that. The people who invented fission were not so stupid they imagined the bomb wouldn't occur, indeed they assumed it would. I have no idea what became of the wisdom of those people.
C) just like nuclear technology that doesn't mean a prohibition is called for. Intelligence is.
What we _can_ do is invest in detection, rapid response technology (vaccines etc), and attempt to mitigate and stratify the possibilities of this happening in the worse ways.
Today's knee jerk prohibitions, and fanciful notions of prohibition working are not facilitating those changes.
