I get why someone would want a short, punchy line about hatred carved somewhere visible — it's raw, honest, and can be a reminder or a warning. When I think about tattoos that touch on hate, I lean toward phrases that either own a feeling briefly or flip it into something wiser. I once sketched a tiny wrist piece that read 'Hate less' after a bruising year; it felt like a quiet rebellion every morning.
Here are short lines I like for tattoos, with little notes on tone: 'Odi et amo' (Latin, 'I hate and I love' — poetic and compact), 'Hate less' (gentle, corrective), 'Hate is heavy' (meditative), 'Hate ends' (hopeful), 'Hate me, don't hate you' (sharp and personal), 'No room for hate' (firm boundary), 'I spit on hate' (defiant), 'Hate burns' (visceral), 'Forgive, not forget' (addresses the aftermath), 'Fuel to dust' (transformative/ambiguous).
If you're leaning toward something permanent, think about context: a short phrase in a foreign tongue can be elegant but research is critical — I double-checked Latin and Japanese characters for a friend and we still did a test stencil. Consider font size (script can look like a scribble if too small) and placement — inner forearm or ribcage reads as personal, knuckles or throat reads as confrontation. And if you want a counterbalance, maybe pair the line with a tiny symbol — a wilted flower, a small flame, or a circle to show an ending. For me, tattoos have to hold a private meaning first; choose a line that won't embarrass you on a cold morning years from now.
