Which is also a valid point. In fact, it would be prudent to remember that even the human characters in fantasy aren't real people.
"If we shadows have offended,
Think but this, and all is mended,
That you have but slumber’d here
While these visions did appear."
-A Midsummer Night's Dream, Act 5, Scene 1
A bit of cherrypickig, there. The piece doesn't support as you might like, as he says, later in that same monologue (emphasis mine):
"Gentles, do not reprehend.
If you pardon, we will mend.
And, as I am an honest Puck,
If we have unearnèd luck
Now to ’scape the serpent’s tongue,
We will make amends ere long.
Else the Puck a liar call.
So good night unto you all.
Give me your hands if we be friends,
And Robin shall restore amends."
So, yes, he offers folks a way to not be mad at him. But, if that doesn't work, he repeatedly says he and and the rest will make it right. You using the quote to dismiss responsibility rings hollow, when Puck himself says he will fix the offense if that's needed.
