Nope, Shika isn't the emotional type. He may feel sad his friend died, but I can't imagine him crying or even being moved to train harder because of it. Besides it wasn't because he was weak that his friend died, it was because Chouji had to use that last pill.

Chouji dying can be a true catalyst for Shika's change in personality.
He may think that if he were stronger or better trained he could have prevented the death and thus he will train only harder to deny further deaths of friends/allies.
I guess you took the pessimistic point of view on this one.
