For a lawful evil character it would make a lot of sense to kill him.
"Thanks for telling me that your body will grant me access to a great deal of treasure. However you ARE guilty of killing two government officials regardless of your excuses and the law is the law as they say. Draw steel!"
and for a Paladin
"It is a sad story indeed, but I am dutybound to pursue you regardless of your story. Since you are not willing to come freely I propose a duel. If you win none of my companions will harm you and you are free to flee. Trust me in this though - should I win I will carry your body with me and rid the world of this Necromancer before I turn you in." and then fight him alone without interference - just turn AI off.

The alignments are always something people debate and interpret. Here are my views:
Lawful - This represents a character that believes in order. The character will generally follow the letter of the law and will abide to agreements as long as he fells they are valid.
Neutral - This character is a person that does not believe in rules, but doesn't always act in self interest either. It is the typical arbiter convincing the Lawful character that since he was cheated he may break his promise and the Chaotic character that it might be more beneficial to leave the gold behind in the long run.
Chaotic - This character always act in his own interest unless he sees some point in not doing so.

Good - This character is benevolent and cares about other peoples wellbeing. He will gladly share his last ration with a starving peasant, but doesn't necessarily do so. He might need the ration to help more people.
Neutral - This character is concerned, but doesn't try to help other people unless it is absolutely called for. He will not share his last ration, but might give one if there is plenty.
Evil - This character is malevolent. He will specifically stop to eat his food in front of a starving peasant even though he is not hungry.

Please note that evil does not mean you always act in self-interest, only that you have a tendency to do so. A lawful evil character will do so as long as he lives up to his promises. A chaotic evil character couldn't care less.
I profoundly dislike stereotypes and like "loose" alignment definitions like above. For starters it gives Paladins a bit more elbowspace and you can create excellent Lawful Evil companions - beware if you are not a friend though. I personally played a LE Templar in the Darksun setting and while the players knew I was colaborating with the Sorceror King the PC's didn't and I was a really good friend and companion torn between my vow to the king and my commitment with the group. I had to give the king tid-bits of information or I wouldn't be able to memorize spells (much like Paladins a Templar will fall if he breaks his vow to the king). Excellent roleplaying if you ask me.

EDIT:
Arggh. I forgot the most important message in all this babble. I don't intend to interfere with YOUR role for your character of course. This is only intended to show which types of characters that will kill Valygar and why.
