I suppose, but I don’t think his mental state indicates that he intended to do that, nor do I think he was at all prepared for that.
All things considered, he inflicted a great deal less damage than he could have. He had enough ammo to fill dozens of magazines, yet appears to have only fired one before taking off.
It’s like he had this big grand plan in his mind, and then suddenly decided to half *advertiser censored* it.
I think he freaked out or lost his nerve, but entered the woods as he intended. Starving, tired, eaten alive by bugs; if he didn’t have the guts to kill himself right away, I think he did eventually.
