It would not do to rule 
according to your emotions.
لا يصحّ أن تحكم العاطفة قراراتك
Doch wenn Ihr nur Eurem Herzen folgt,
wird Eure Regentschaft von kurzer Dauer sein.
No bastará que gobierne
según sus emociones.
No bastará que gobierne
según sus emociones.
Vous ne pouvez pas

Non dovreste farlo 
seguendo le vostre emozioni.
Comandar seguindo suas emoções
não seria uma boa ideia.
Негоже вам идти на поводу у чувств.
