Up to September, 2019 you can check here: https://mrthomsen.de/player/death (you can also check who you killed)
In my opinion this is the most complete list. In other websites, like guildstats, many of my deaths are missing, but in this one I can see all of them.
Sadly, its not being updated anymore, so you check it there, up to Sep/19. After that you can use:
Guildstats: https://guildstats.eu/character?nick=fire%20draggon
Tibiaring: https://www.tibiaring.com/char.php?c=FIRE+DRAGGON&lang=pt
