Is it still kill stealing if.....

[Skoshi Tiger]

Just to see what the concensus on this situation is.

Flying in a New Guinea map on line and there is a three way chase, a Red plane - a Zero - and another red plane comming up the rear and I'm above the action looking down

The zero is shooting at the first Red plane when the trailing red plane gets hits on the zero which starts streaming smoke and flames.

Unfortunately the Zero does not break off or eject , but continues to stick on the first red planes tail blazing away with all guns.

At this point I've lost track of the trailing red plane so I drop down on the zero and finish him off!

Of course this all takes place in the course of 20-30 seconds so there wasn't too long to think about it.


Am I:
a) A Hero for saving my team mates life?
b) A dirty scum sucking kill stealer?
c) A dirty scum sucking kill stealer that will sleep well tonight in the knowledge I saved my team mates life?
d) Very lucky I didn't get any shots on the first Red plane and shoot him down instead?

What do people think?
