Based on a video where the author talks about the three most dangerous types of people in real life - those with nothing to lose, those who have often faced violence, and hidden predators. Let's transfer this to Eve: 

Nothing to Lose

The first most dangerous type of capsuleers is those with the feeling that they have nothing to lose. In real life, these could be homeless people, drug addicts, since they don't have a family, home, etc. holding them back. I have two examples in Eve. 

The first is that a co-corporate flew to Pochven on a magnate for 1kk, he bought up in Jita and never took the filament back. I asked him why, he answered that he is not flying to live, he is flying to die and in between looting salvage, dropping it off at the NPC station in Pochven. Indeed, when you have 100-1000 spare attempts on a ship (magnate, cormorant, thorax, cyclone, praxis), then there is a feeling that there is nothing to lose in principle, and if you also have an alpha account (or pay in real money), i.e. no need to farm 50 plex every 3 days, everything only gets worse. 

The second example, if all your structures or your corporation were demolished. After that, it is no longer possible to agree on anything since there is no longer a factor that holds you back. For example, in Planetside 2 you can never drive one of the factions to the warpgate, but always leave 1-2 bases and switch to another race because you can't capture the spawn. If you don't do this, then the squeezed faction fully switches to yours and victory on the continent no longer becomes its main task. Their task will be to specifically take away as many bases from you as possible. 

Lots of experience in violence

In the author's video, examples are MMA fighters, street fighters, police and those professions/occupations where you have to deal with violence every day. That is, you poke a finger at such a person, and not only will he turn it inside out, he will also shove it somewhere and show that you can actually do more to a person than you think. Because ordinary people and those who often face violence have very different boundaries in terms of what can be done and what cannot be done. 
In our game, these are places with a lot of PvP: Frac War, Pochven, WH, Low, Null, Ganking in Highsec. Often such people have a negative security status, because they have to blow up a lot of ships or capsules. But it is not necessary, security status can be washed.

Socorp from the example on the Magnate, who farmed Pocven, then evolved due to an excessive amount of PvP, when looting the Salvage of Triglav. He put a scrambler, guns on the magnate, in parallel with the farm, he killed all the T1 frigates that he could catch and defended himself. Well, the magnate went up in price from 1kk to 12-16kk. 

Hidden Predator

This is a representative of the first or second type, but you did not recognize a threat in him and took him for an ordinary person. Like an MMA fighter goes to a friend with a chessboard to play, this does not mean that he is a chess player, but you can decide at first glance. 

In Eve, for example, this often happens, you look at the board, the pilot is farming for himself on a Vexor, and then it turns out that this is a suicidal Vexor with 600 dps. Or you are mining in lowsec, Venture warps to the belt, mining something, it can be a blaster and with a scram, or Venture lights a cyno on which several black ops jump and shoot your ship. 
The winter event is the same, endurances with blasters in lowsec. Then praxis baits with a scram, which is impossible to neutralize on the gate. The Hidden Predator can be partially recognized by the killboard, but this method does not always work. Mimicry for PvE or a newbie.
