I don't think that's the reason anyway Dragon Slayer Magic IS for killing dragon that's why they call it Dragon Slayer Duh!

I just have a feeling that Igneel would see Natsu, Igneel wishes that Natsu must defeat or kill him in order to be able to defeat Acnologia an ultimate sacrifice and maybe same with Wendy and Gajeel but that's just my opinion.
