honestly i doubt the psychedelics played any part into it if he did do them.  you need to consider what we do know about him. he was living an extremely comfy do nothing and win life that then got compromised by an injury that persisted even after most likely pretty solid treatment. so he decides he has been robbed of his perfect life and goes after the easiest target he can get to. granted my take requires him being a dumb spoiled kid that then got made life got fucky and blamed and took it out on what he could. which is pretty on point to his generation and social classes standard
