Is this normal for a very young boy to do?

“My youngest self, with pure idealism and a love for all things, and all people, unconditionally, would find a warming fulfillment in being cruel- not to any living thing, mind, because he loved and treasured all living things unconditionally, and wanted to be good and kind- but to little plastic dolls? They were to play with and to have fun and games; so there is nothing wrong with playing cruel games.
I loved the castle I constructed for them, because it had a dungeon; I used the dungeon the most in every game, and there was the divesting of rubber clothes, and there was betrayal, torture, death, humiliation and agony. :/ They would be tied with string, and hung, et c.- and this young self was yet innocent of all things.
I only enacted such games and theatre, because it gave a contented warmth and granted a smile; nothing and no-one else did. I did not understand that any of it was less than good- somehow- but only that it was delightful.”
