No you shouldn't.
Many deaths are caused by inadvertence or bad luck - what's to feel sad about?
When you enter for the first time a Tier 5 POI it's easy to die due to trap rooms, ambushes, false floors etc. It's not your fault you are not familiar with their locations yet.
If you watch some...
POIs with neatly concealed main stash room exit - like the Mortician's house.
It's amazing how close you were to the main stash room direct access from the get-go, and didn't see it in plain sight
Something doesn't add up...
Recently I was surprised to see like dozen of Demolishers during the horde night in Single player in the Forest biome.
My Gamestage was just ~105. I expected so many Demolishers to appear only at GS 170-180
- Build a combined crafting + horde base, even if you don't intend to fight blood moon hordes.
- Locate your base in the Forest biome.
- Mine iron and lead underground only, not too close to the surface with a tunnel leading to your base.
