If the aliens are capable of independent flight, drunk flying would be viewed similarly to how we view public inebriation. But if they're flying via flying cars, then drunk flying would be akin to drunk driving.
For a flying alien, suicide via not flapping your wings might be as difficult as it is for yourself to kill yourself via not breathing.
For egg laying aliens, abortion might be easier to accomplish and to hide the evidence of it, but I think the societal stigma would still be there. If anything, comparisons to murder might be even more legitimate, as the egg isn't directly reliant on your body to develop.
