Meaning of そういうことだ here


The character lied to someone and then narrated

> 優しい嘘もこの世にはある。 **そういうことだ** 。

I understand that there are a variety of meanings that this phrase can add but
I am unsure what it is adding to the whole here. For example, how would this
line have been interpreted differently if そういうことだ was removed completely?




そういうことだ is a statement of agreement, "That's it", "That's true", "That's what
I wanted to say", "That's how it is", etc. Here, the speaker is confirming
with himself what he just thought, so "That's how it is" or "That's the way it
is" would fit.
