But I can if I want to.
In a sense, the lack of reward for direct PvP is a consequence of allowing non-Open modes. There simply isn't enough risk involved in killing other players unjustifiedly since they are treated just like NPCs for game-play purposes. Killing players shouldn't be made into something special, there should be no score kept to separate between killing of PCs and NPCs. There should be consequences though (which there isn't, really). And that's why Groups and Solo seem like ways to avoid the bad apples.
Think about it. We kill, get killed and respawn. To make that make sense, we must have a deal that allow us to be cloned from a database and an insurance that doesn't mind the reckless behaviour. But what if the Pilot Federation actually had to strike deals with powers and factions to do this? What if the respawn feature was available everywhere, but the most developed systems generally had an agreement with the PF about when to allow for a Pilot to respawn?
That way if you kept committing crimes, the most developed, stable and connected systems might refuse to let you respawn at their stations. If you die in their space, that's it. Start from scratch. Or you are given a Scarab with a mining module and set to break rocks somewhere until you have repaid your bounty. The baddies would slowly be restricted to play in the most anarchic systems that may not strike deals with the Player Federation.
That could even make it a little exciting to be an outlaw...
