Not quite exactly what you are asking for, but you may be interested in this answer from /u/Myrmidon99 while you wait:
No there was no stigma attached to bailing out of an aircraft, and was actually encouraged. Kamikaze pilots were even expected to return home if they felt that they could not successfully carry out an attack. Pilots were very valued. I am sure it was better to return home victorious, with your aircraft, but having a skilled and trained pilot alive was better than nothing (surrendering to the enemy willingly was of course frowned upon however, and you were expected to take your life to avoid capture).
When it comes to being wounded I am not aware of any stigma for this. The Japanese were famously undersupplied, and did not have medics. Accommodations for the wounded were limited, but I am sure this was an expected part of war, and not frowned upon (I am more knowledgeable on Japanese aircraft and pilots though, so I am not 100% sure on this).
