What does the "きゃ" in "していきゃがらなかった" stand for?


I read this phrase in a visual novel:

"こいつが出かける前に、きっちり支度をしていきゃがらなかったからじゃねぇかっ！？"

I don't get what the "きゃ" means in this context. If it's short for "ikeba", I
can't make sense of "がらなかった" ("didn't show any signs" of what? ) and if it's
something different, I don't have a clue.




> 「していき **ゃ** がらなかった」 with a **small** ゃ

The "dictionary" form of that is:

> 「していき **や** がらなかった」 with a regular-size や

The components are 「する」、「行{い}く」、「やがる」 and 「なかった」.

Thus, the sentence in question is in the Kanto tough guy speech.

> "That's because this dude hadn't made proper preparations before leaving
> (home), ain't it?"

I didn't make it sound too tough, did I?
