Tambourine and Drum is an interesting case and I really can't find too much justification (also because it's been so long since I seen this part) King Piccolo himself is in good actions because Piccolo was a threat to the world and could've ruled the world.
Yes, Goku fully intended to kill Freeza at the very end (and for a while, was under the assumption he DID kill him) but he was lenient and gave him some energy to escape, sparing his life so this is debatable. Yakkon was basically a throw away character and just meant to be a small annoyance. Maybe you could argue that his death was an accident but I don't really buy it, Yakkon didn't really stand a chance, assuming the room was still fully lit. Kid Buu is kinda like Freeza, he did kill him but it was in protection of the Universe! He also wished for Buu to be reborn as a good person so that may effect things.
In Super, the continuity has already been fucked so him killing Freeza isn't really special. (I believe he did give him some chances to surrender)
Overall, Goku hasn't used the Nimbus since Z (they always show it in the ending credits for nostalgia) so it doesn't matter.
