Answer 1

1. Where does the notion of "this bad" come from?

It's from この程度, which literally is "this much", "this degree" or "this extent". More verbosely, this could have been この程度の悪さ ("this degree of badness").

2. What nuance is the "も" adding to the sentence?

This is も used to make the sentence sound reserved. See this question: Meaning of く も in this sentence
