I found this:

```

    でも、考えてみればだ。
    
```

Actually this is the first time I've seen a だ with a conditional together.
What does it mean?

question
grammar conditionals copula
conditional ば with だ？
I don't have any academic knowledge, but my sense as a Japanese speaker is
that it has the role of emphasizing the speaker's words. That is something you
see in novels, but I don't think it is used very often in everyday life. From
a Japanese point of view, it may give the impression of someone who is
assertive.

The following is just my imagination. The word "だ" has the meaning of fact or
assertion, which may have been derived to include the meaning of emphasis.
