I am a peaceful man, with bad intentions

ダメ人間

Pulvis et umbra sumus. [We are both dust and shadow]
(Horace - Odes)

Me pinguem et nitidum bene curata cute vises, cum ridere voles Epicuri de grege porcum.
[You may see me, fat and shining, with well-cared for hide,—…a hog from Epicurus’ herd]
(Horace - Epistolæ)
