Foolish, yes. Means he is unskilled? No.
That level of foolishness effects his combat effectiveness though.
It's not like when Kenobi beat Maul in TPM where it seemed to Maul he'd already won but he just made that one error forgetting about Qui-Gon's Saber.
In Kylo's case he was bleeding out, yet Still Chose to not only face his opponents alone but to also Toy with them and that stupid decision cost him. So we have to wonder what other stupid decisions he may make in combat that would cost him.
