Yudhistar another name isc ajaat shatru ( means one who have no enemies) but did yudhistar really don't have enemies ?
Duryodhan shakuni, dussasan karn wanted yudhistar to die along with pandav and kunti in laksh grah
Shakuni duryodhan did send yudhistar to vanvas along with pandav and draupdi
Then virat king hit yudhistar ( because yudhistar give credit to Arjun that because of Arjun,uttar able to defeat duryodhan,kripacharys bheeshm ) nose and yudhistar nose started bleeding. ( it is yudhistar forgive virat king and tell draupdi to stop arjun coming here, if he see my nose bleeding then he will kill virat king)
Now drona charya duryodhana making plan to arrest yudhistar
So in what way yudhistar don't have enemies?. It is another thing yudhistar did not considered anyone his enemies most of time except shalya
