Help me parse this sentence, why does it use volitional form?>目撃されようと、証拠を残そうと、絶対に捕まらないのだから気にしなかった。

Hi, all.

This is a bit from a short story I read, but I can't figure out why it's using the volitional form. I did some research and I can only find instances of 気にする being used with ordinary direct objects, like nouns and nominalised verbs.

Thanks in advance or any intel.
